Dichroic Color Filters
PIXELTEQ’s red color filters provide consistent vibrant color for all kinds of illumination and detection applications. The long wave pass dichroic filter design transmits only the longer red visible wavelengths and reflects shorter visible wavelengths. Also known as thin film or interference filters, PIXELTEQ’s red color filters use multi-layer hard sputtered coatings that provide durable shift-free performance without fading or aging in high output luminaires.
Dichroic Color Filters vs. Absorption Filters
Unlike absorptive colored glass or polymer gels, these thin film interference filters are virtually absorption free – providing superior transmission, rich saturated blue colors, and true lifetime performance. The red color filters also have a steep edge transition between the shorter wavelength reflection band and the longer wavelength transmission band – much steeper than colored glass or polymer gels.
OEM Custom Options
Custom colors are available to match specific cut-on wavelengths and calibrated CIE colors – engineered for your specific illumination source & optics to deliver the targeted color output. These color filters can be patterned on gradient wheels or flags for smooth variable RGB or CMY color mixing. Multiple colors can also be micro-patterned for full color and photorealistic imaging effects and gobos. In addition to customized coatings, the optics are delivered in the form to fit your application – in specific substrates, shapes, and sizes.
Color filters are commonly matched or combined with other types of filters to optimize performance in your specific application. In many cases, an optimized OEM design combines multiple coatings onto the same optic to enhance performance, size, and weight of the device. Some of these complementary filter types include:
- UV – IR filters: transmit visible colors while blocking harmful Ultraviolet and/or Infrared light
- Cold Mirrors: reflect visible light into the illumination path while transmitting infrared light & heat through the rear of the reflector or outside the device
- Color Correction filters: adjust the correlated color temperature from one type of lamp to match another
- Patterned Color Filters: smooth mixing from full to zero color saturation, plus combinations to precisely mix wide and rich color gamuts
- Color Gobos: multi-color and full color gobos micro-patterned for high resolution photorealistic images and effects
