About the products 

Semrock's optical filters are manufactured using a proprietary hard coating process. This produces filters with the highest brightness, contrast and ruggedness currently available.

The filters let you push the limits of signal-to-noise in your instrument design. Steep edges maximize the bandwidth that can be accessed in each detection channel, while high transmission or reflection captures every photon possible. Deep and extended blocking capabilities out of band are optimised based on your application, reducing noise and minimizing crosstalk between channels.

  • Fluorescence filters: single band, multiband, laser line, tunable
  • Edge filters: longpass, shortpass, ultrasteep, 29 laser wavelengths
  • Dichroic beamsplitters: broadband, laser, multiphoton
  • Laser filters: clean-up, ultrasteep edge, dichroics, notch

The outstanding quality of Semrock filters is backed by our industry-leading 10 year warranty and 30-day free trial of standard products.
