New compact Echelle System ESA 4000plus

Echelle spectrograph ESA 4000plus

ESA 4000 changes to ESA 4000plus

Starting in january 2016, Echelle spectrograph
ESA 4000 will get a completely new design of the spectrometer chassis.

The optical chamber is hermetically sealed. Due to the integration of a dustless molecular sieve, humidity in optical pathway is clearly reduced. The new chassis is particularly suitable for industrial usage.

The new Echelle spectrograph ESA 4000plus is orderable from january 2016.
