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
