Description

For those who already have an Alpy 600 spectrogrpahe, this optical core module gives you a low-cost Alpy 200.

You’ll need to use the mechanical part of your Alpy 600 as well as the slit, which is not supplied with this module.

Note: It was Robin Leadbeater who first suggested – several years ago – that we make a variant of the Alpy 600 for observing weak targets. Thank you Robin !

 

Specifications

  • resolving power: R ~130 with 23µm slit
  • Aperture : F/4

Composition

– optical module with grism of 200 gr/mm
