- Wavelength ranges from 185 nm up to 1100 nm
- Hamamatsu or Toshiba linear detectors; entrance slit 20 µm as standard, user-replaceable
- Numerical aperture 0.16; stray light about 0.08 %
- SMA fiber input
How to choose
Choose the wavelength range first, then the detector: back-thinned Hamamatsu sensors for UV and low light, the Toshiba TCD1304 for economical visible work. A wider slit gives more signal, a narrower slit better resolution.
