Color Filters

Home Products Components Optics Filters Color Filters

Color filters absorb specific wavelengths of color and transmit the non-absorbed wavelengths, making them visible. As a result, our color filters provide consistent vibrant colors for many illumination and detection applications. In addition, unlike polymer gels or colored glass that absorb other materials, these thin interference filters are virtually free from absorption, providing superior transmission and lifetime performance.

We design our dichroic colored filters to efficiently transmit certain regions of the visible spectrum while reflecting others. Unlike some polymer gels or absorptive glass filters, our thin-film filters provide superior transmission while remaining absorption-free. Our rich amber color filters also have a much steeper edge transition between the longer and shorter wavelengths than colored glass.

The light produced by dichroic filters is saturated in color, presenting exceptional uniformity and purity. Also known as interference or thin-film filters, our amber color filters use hard, multiple-layer coatings to allow stable performance without aging or fading under high-output lighting applications.

Some of the applications of our amber color filters include:

Entertainment, architectural and technical lighting.
Sensing and imaging.
Machine vision technology.
Cinema and digital projection.
Copy and print processing.

Benefits of Amber Color Filters:

Because our color filters reflect undesired wavelengths, they do not absorb unwanted energy during operation. As a result, they do not become near as hot as typical glass filters. This feature makes them ideal for the highest-powered lighting systems, including those found in filmmaking and concerts. In addition, our amber color optical filters will not degrade, melt or deform in standard applications.

Salvo Technologies amber color filters offer a far longer life span than most traditional filters. In addition, because the color forms part of the layers, it will not bleach out over the filter’s lifetime. This attribute is essential for cinema and theatrical shows where structural integrity is critical.

Among the benefits of amber color filters are:

Indoor and outdoor spectral stability.
Customization to original equipment manufacturer (OEM) requirements.
Structural durability for high-intensity lamps.
High transmission and low absorption.
Long performance with no aging or fading.

We supply amber color filters in two stock options:

Amber 590nm LWP: Wavelengths from our Amber 590 LWP color filter can measure up to 590 nanometers in the long-wave pass (LWP) regions.
Deep Amber 595nm LWP: Wavelengths from our Deep Amber 595nm LWP can measure up to 595 nanometers in the LWP regions.

Companies unsure of their exact specifications can test a specific stock filter before committing to a higher volume purchase. We can ship most of our stock orders in as little as 24 hours.

Besides our stock options, our amber color filters are fully customizable. Simple customization is often as easy as choosing between the type of filter, the dimensions, and a circular or rectangular shape. We can sometimes apply multiple coatings to the same filter to enhance performance or alter the effects.

Our amber color filters can integrate with some of our other designs to optimize productivity. Options include:

Infrared (IR) and ultraviolet (UV) filters.
Color correction filters.
Patterned color filters.
Color gobos.

Our dichroic color filters, also known as interference filters, filter light by blocking all undesired wavelengths while permitting selected wavelengths to pass through. We construct our color filters using thin-film technology by applying several film layers on one side of an optically flat piece of transparent, borosilicate glass. When light hits the coated side of the filter, the different film layers transmit and magnify the desired wavelengths while reducing or reflecting the unwanted wavelengths entirely.

Compared to absorptive optical filters, interference filters significantly improve selectivity and are much more effective in precision applications. Our cyan color filters block red light, allowing green and blue to pass through. Several typical applications of cyan filters include:

Original equipment manufacturing (OEM) sensing and imaging.
Architectural, technical, and entertainment lighting.
Machine vision applications.
Copying and printing.
Benefits of Cyan Color Filters

Coating Options

We can add multiple coatings to our cyan filters to produce an enhanced or altered effect. Our color filters also combine well with other designs to optimize performance. Some examples include:

Color correction filters: By absorbing specific wavelengths, these filters can adjust the color temperature of a light source.
Patterned color filters allow for smooth mixing from zero to full-color saturations.
Color gobos: These can effectively change the shape of light, providing altered effects.
Infrared (IR) and ultraviolet (UV) filters: These designs accurately transmit visible colors while blocking harmful IR or UV light.
Cold mirrors: Cold mirrors reflect visible light while transmitting heat and infrared light outside the device.

Our dichroic color filters, also known as interference filters, use multiple layers of thin materials to control transmitting or reflecting wavelengths through constructive and deconstructive interference. Our fuchsia filters measure wavelengths in the long wave pass (LWP) region, meaning they effectively transmit long wavelengths while blocking or reflecting shorter ones.

We design our color filters using nonabsorbing materials, which provide superior transmission of rich colors while minimizing light loss. Our filters also allow for a much steeper edge transition between reflection and transmission bands than most traditional designs of color filters. These features essentially project and control specific colors to appear brightly and efficiently.

Interference filters are perfect for precise scientific instrumentation, as their reflection and transmission curves are highly controllable, allowing for very sharp transitions and narrow bandpass regions. Other industrial uses of our color filters include:

Enhanced lighting in theaters and concerts.
Machine vision technology.
Print and copy applications.
Sensing and imaging for original equipment manufacturing (OEM) devices.

Benefits of Fuchsia Color Filters:

By controlling the number of layers and coating thickness, the wavelength of the filter’s passband is adjustable both ways. Because unwanted wavelengths reflect rather than absorb, colored optical filters don’t become nearly as hot as the equivalent conventional filter under heavy-duty lighting applications. Several added benefits of our fuchsia filters are:

They provide more efficient results than traditional absorptive filters.
Optical Filter Shop’s interference filters effectively repel heat under strenuous conditions.

* Our color filters do not age or fade, unlike gel filters.

Our filters are highly durable and will not melt or deform.
They feature high transmission and low absorption properties.
Our color filters provide spectral stability indoors and outdoors.
They’re fully customizable.

We can pattern other filter designs with our fuchsia filter to produce full color and photorealistic imaging effects.

Additionally, we stock one filter that falls within the fuchsia color family. Wavelengths from our Purple 682nm LWP color optical filter can accurately measure up to 682 nanometers in the LWP region.

Our stock options allow perfect prototype opportunities without committing to an expensive, larger-lot order. In addition, quick alterations of our fuchsia filter make for easy customization. In most cases, ordering a custom fuchsia filter is as simple as telling us the shape and specifying the dimensions.

We can also apply multiple coatings to our fuchsia color filter to alter the weight and size while enhancing its performance for a specific application. The fuchsia filter can also combine with other stock filters to provide even more versatility. Several examples of potential pairings include:

Infrared (IR) and ultraviolet (UV) filters.
Cold mirrors.
Patterned color filters.
Color correction filters.
Color gobos.

Our dichroic color filters use thin-film technology to interfere with specific wavelengths selectively. We construct our color filters using multiple layers of coatings and adhering them to an optical borosilicate glass substrate. Our green color filter design transmits only the central green visible wavelengths while reflecting the shorter blue and longer red visible wavelengths.

Our green color filters use unique, hard-sputtered coatings that provide lasting durability and shift-free stability without fading or aging under the most intense light applications. While many traditional color filters are absorptive, Salvo’s color filters are absorptive-free, allowing for enhanced transmission and rich, saturated colors. Our green interference filters also feature steeper edge transitions than most conventional color filters, allowing optimal light transmission.

The thickness of the optical layers determines the filter’s specific performance characteristics. As a result, green interference filters can effectively meet the needs of many industries like spectroscopy, agriculture, chemistry, and photography. Several specific applications of our green filters include:

Copying, printing, and xerography.
Machine vision systems.
Imaging, sensing, and tomography.
