Photon RT Spectrophotometer


World’s first spectrophotometer designed for coaters.

World’s only instrument to feature UV-MWIR (220-4900 nm) polarization measurement capability in a single device, a unique opportunity to get deeper insight into performance data of optical coatings.

The PHOTON RT UV-VIS-MWIR scanning spectrophotometer is designed specifically for unattended measurement of optical samples with coatings. The instrument can be produced in six configurations relative to the effective wavelength range meeting individual customer measurement needs – from 380-1700 nm up to 190-4900 nm.


Polarizing and beamsplitters cubes, X-cubes
Broadband antireflective coatings
Laser mirrors and standard flat mirrors
Interference filters:
- Longpass
- Shortpass
- Dichroic
- Multi-band coatings
Prisms and wedges
