When coupled to an Ocean Insight miniature spectrometer, the FHS-UV is a handy tool for measuring absorbance/transmission and other optical characteristics of filters. The FHS-UV accepts round filters up to 25.4 mm (1”) diameter, and square filters >12.7 mm (0.5”) and up to 6 mm (0.24”) thickness, and is a convenient alternative to awkward optical filter setups.


  • Convenient – ideal fixture for measurement of optical filters
  • Flexible – accommodates filters up to 25 mm diameter and 6 mm thickness
  • Collimated light – includes a pair of collimating lenses to optimize throughput
