High performance slit 23µm

This 23µm “high performance” slit differs from standard slits in the following ways:

1. The coating is made of protected aluminium, which provides a reflection rate of over 90% (compared to ~50% on standard chrome slots).
2. The reflective surface is larger: useful for example if you use an IMX174 sensor on your guidance camera with an Alpy guidance module.
3. The anti-reflection treatment has been extended to cover the 350-800nm range; this is particularly useful with UVEX which covers a large spectral range.

This slit is compatible with the ALPY 600 and UVEX spectroscopes. It is particularly recommended for UVEX.
