Dichroics and Color Correction Filters
Dichroic color filter coatings are an excellent alternative to dyed plastics and glass when a beam of light must be split into two distinct beams varying by wavelength. Color correction filters alter the overall color of light to achieve a specific color and sometimes to obtain a specific color temperature. Unlike plastic color gels which age and breakdown quickly during use, dichroic filters and color correction filters are designed to stand up to the heat and UV energy in high energy light sources. High energy light sources can also have a damaging effect on dyed glasses as well, due to their heat absorbing nature.

 

Dichroic and color correction filters have the advantage of reflecting unwanted light instead of absorbing the energy, which allows dichroic filters to be used with much higher intensity light sources up to 550°F.

 

Dichroic color filters are used in a variety of applications including architectural, entertainment, scientific instruments, and engineering. Many industry standard colors have been engineered as dichroic filters.

 

We have over 160 different colors available. Dichroics are offered from 1.1mm (.043”) thick up to 3.3mm (1.28”) thick.

 

Standard Additive Blue
The Standard Additive Blue color coating has an average transmittance more than 85% from 390-480nm, 50% point at 505nm ±15nm, and average transmission less than 1% from 540-750nm at normal incidence.

Standard Additive Green
The Standard Additive Green color coating has an average transmittance less than 1% from 400-460nm, 50% point at 505nm ±15nm, peak transmission at more than 70%, 50% point at 575nm ±15nm and average transmittance less than 1% at 610-710nm at normal incidence.

Standard Additive Red
The Standard Additive Red color coating has an average transmittance less than 1% from 390-550nm, 50% point at 605nm ±15nm and average transmittance more than 75% from 620-730nm at normal incidence.
#5, g01-625 Standard Red

 

Standard Subtractive Cyan
The Standard Subtractive Cyan (Anti-Red) color coating has an average transmittance more than 85% from 400-550nm, 50% point at 590nm ±15nm and average transmittance less than 1% from 640-720nm at normal incidence.
#6, I00-467A Standard Cyan

 

Standard Subtractive Yellow
The Standard Subtractive Yellow (Anti-Blue) color coating has an average transmittance less than 1% from 410-475nm, 50% point at 515nm ±15nm and average transmittance more than 85% from 550-750nm at normal incidence.
#6, I01-055D Standard Yellow

 

Standard Subtractive Magenta
The Standard Subtractive Magenta (Anti-Green) color coating has an average transmittance more than 80% from 380-470nm, 50% point at 485nm ±15nm, average transmittance less than 1% from 535-565nm, 50% point at 615nm ±15nm and average transmittance more than 80% 655-750nm at normal incidence.
#6, I00-526A Standard Magenta

 

Color Temperature Blue
A variety of standard color correcting filters are available including Color Temperature Blue (CTB). A Full CTB filter converts a 3200K light source to 5500K. Most filters are stocked in 24″ diameter x 3.3 mm thick Borofloat®. Additionally, CTB filters are available in shades with lesser color temperature shift.
#7, H01-932 Full CTB

 

Color Temperature Orange
Another standard color correcting filter is Color Temperature Orange (CTO). A Full CTO filter converts a 5500K light source to 3200K. Most filters are stocked in 24″ diameter x 3.3 mm thick Borofloat®. CTO filters are also available in shades with lesser color temperature shift.
#7, G99-521 Color Temperature Orange

 

At Abrisa Technologies, we have over 160 different standard dichroic color in stock. These long lasting filters can withstand up to 550°F. All dichroics are 1.7mm (0.69) thick unless noted and are on SCHOTT Borofloat®.
