Optical Filters

Fluorescence Filter Sets offer optimized dichroic beamsplitters.

Available for use with DAPI, GFP, FITC, mCherry, Texas Red, and many other fluorophores, BrightLine® Filter Sets feature optimized dichroics with extended reflection and transmission bands. Each dichroic reflects light from long-pass edge down to UV wavelengths less than 350 nm and transmits light from edge up to IR wavelengths greater than 950 nm. With anti-reflection coating, dichroics...

Optical Filters

Long-Pass Fluorescence Filters feature no burn-out design.

Targeted at imaging DAPI, GFP, and red fluorescent proteins, BrightLine® Long-Pass Fluorescence Filter Sets allow users to choose between narrowband excitation filter to minimize photobleaching and phototoxicity to sample, and wide exciter for maximum signal in very low-concentration samples. Emitters offer greater than 93% average transmission over passband and extremely steep edges that...

Optical Filters

Infrared Longpass Filters isolate broad spectrum regions.

Useful for FTIR spectroscopy and thermal imaging applications, Infrared Longpass Filters provide sharp cut-off below particular wavelength and are often used for order sorting. Units simultaneously provide high transmission of desired energy and deep rejection of unwanted energy. Constructed with hard first-surface dielectric coatings on optical-quality IR-transmitting substrates including...

Neutral Density Laser Beam Filters cover UV wavelengths.

Comprised of modular, slide-in, neutral density attenuators and C-mount holder, UV ND Filter system attenuates UV laser beams so they are at proper intensity for CCD or Pyroelectric cameras. Filters work on lasers in 190-380 nm range and are made from Fused Silica with Inconel coating on one surface to effect attenuation of incident light. They are also tilted to eliminate any parallel,...
