About this product
Part Number: Alpy600photometricslot23
This photometric slot for the Alpy 600 Spectroscope (for use with the guidance module only only ) contains two different slot widths (in line with each other). The narrow slot (23μ) exploits the full resolution of the Alpy 600. The wide slot (200μ) completes this observation with a spectrum that integrates all of the light of the star - allowing a photometric measurement.
