Custom Circular Variable Neutral Density (CVND) filters change light intensity from 100% to less than 0.1%. Densities are supplied 0 to 1, 2, 3, 4, or 5 as a standard linear or customized gradient function, which can range from 45° to 360° of rotation. Features include laser and broadband coatings, substrates from 1- to 8-in. diameters, and functional wavelength from the UV to the far IR.

Chroma understands that Raman scattering is a weaker signal requiring much better filters, with steeper edges, to isolate the signal of interest. Our Raman filters or sets will cover a wide variety of spectral ranges for your project when you need higher transmission values, steep transitions, and superior blocking to keep out unwanted photons.
