Product Details

Ocean Insight makes available high-quality glass filters that absorb light energy in certain regions of the spectra. These OF2 series filters fit easily into our light sources, cuvette holders and sample holders for a variety of applications.

  • High-pass filters often are used to block second orders, test for stray light and block excitation energy in fluorescence and Raman experiments.
  • Balancing filters absorb energy in some regions while transmitting in others. 
  • Bandpass filters transmit a particular wavelength range while rejecting energies higher and lower than the selected range.

Product Overview

  • Multiple options – selections include high-pass, low-pass and balancing filters
  • Convenient – filters install easily into the optical path of your spectrometer setup
  • Glass material – precision absorbing filters for visible wavelength region
