Chroma’s expertise in optical interference design, coupled with our highly precise thin-film deposition technology, results in the most advanced optics available. Raman scatter is a weak signal requiring high-performance optics with steeper edges and broader, flatter transmission bands to isolate the signal of interest. Chroma Raman filters are the ideal solution for your project when you need higher transmission values, fast transitions, and superior blocking to keep out unwanted photons. Chroma’s Raman optics provide extremely steep transition slopes from transmission to blocking and/or reflection, highly precise passbands, and extremely high out-of-band blocking to provide the highest obtainable Signal-to-Noise ratios (SNR). Our filter sets include a narrow-band laser clean-up filter matched with a laser dichroic mirror paired to a longpass barrier/emission filter, each with sheer spectral slopes. Together, these optics allow for the detection of even the faintest Raman signals. You’ll find Chroma’s sputter-coated optics in labs throughout academic, medical, pharmaceutical, and biotech institutions—and used by researchers exploring revolutionary scientific advancements, developing life-changing medical treatments, and ensuring the safety and security of lives across the globe. Beyond Standard Offerings Our catalog of standard Raman filters and sets are designed for the most common Raman wavelengths. Our expertise in optical filter technology is matched by a deep understanding of Raman applications.
