Dichroic Coatings

Dichroic coatings offer a permanent color solution that will not degrade or fade over time. Dichroic coated filters transmit the desired wavelengths and reflect the unwanted wavelengths, resulting in a high transmission coating with little to no absorption. Dichroic filters are designed for applications that require precise color of the spectral band. We produce many types of dichroic filters on glass and polymer substrates for color division applications such as entertainment lighting, specialty imaging, color correction and light trimming.



Features:

  • Can be coated on glass or plastic substrates
  • Our standard glass dichroic filters are coated on Borofloat® borosilicate glass
  • Can be coated on tempered patterned/diffusion glass lenses
  • All of our dichroic filters are manufactured by vacuum deposition
  • Coatings can be designed to match almost any color
  • Will not fade or degrade over time
  • Minimal absorption unlike solid colored glass filters which subtract light by absorption
  • Operating temperature up to 375C
  • Can be frosted on uncoated side for diffusion
  • Used to manipulate the color temperature and simulate various types of light sources (see color correction filters)

 

Dichroic Colors

Below is a list of colors which are commonly inventoried. Any color may be designed or shifted to meet customer’s specific requirements. If our customer does not have a color sample to send us for photometric analysis, we can design colors based on a Rosco, Lee, Apollo or Gam theatrical gel number.

 

Color Correction Filters

Color correction filters are designed to shift the Kelvin temperature of a lamp. CTO stands for color temperature orange. These filters are also known as skintone filters as they are typically used to improve the appearance of natural, warm colors, especially skin colors by warming the light. They are ideal for restaurants, hotels, restrooms, retail stores or anywhere people come together. CTB stands for color temperature blue. These filters are known as daylight conversion filters and are designed to cool light. They may be used in downlights or directional luminaries to adjust a warm light or halogen to match daylight.


LED's
Our durable polycarbonate and glass dichroic filters designed for LED’s can help you achieve quick interchangeable filtering to meet any of the following lighting requirements you may have:

  • Color correct the harsh light of white LED’s or cool a warm LED
  • Introduce bright color saturation and dramatic lighting effects with over 50 colors to choose from
  • Trim the light output using our neutral density LED dichroic filter coatings
  • Increase the light output with our highly transmissive anti-reflective coatings
  • Diffusion, silk screening, custom printing, hole drilling, can be added to any of our filters

These filters offer an affordable alternative to replacing the actual LED lights and the glass or polycarbonate cover offers added protection to the LED pod.


Typical Applications:

  • Lighting
  • Architectural Lighting
  • Entertainment Lighting
  • Fiber Optic Color Wheels
  • Light Correction Applications
  • Electronic Devices
  • Heat Control Applications
  • UV Control Applications
  • Underwater Lighting
  • Medical
