More about the series Alpy...
Behind the name Alpy lies a product line for spectroscopy: astrophysics without an astronomical budget!
The modular Alpy system: The core element is the Alpy 600 spectrograph. It allows you to work in a range from near UV to near infrared. Thanks to the standard connections and accessories, you can adapt the spectrograph to your existing optical system and sensors. The basic module can be used as a photographic slit spectrograph or for visual observation. With the Alpy Guider, you can achieve longer exposures. The Alpy calibration module enables wavelength calibration and the generation of flats. Thanks to the Alpy barlow lens, you can use a DSLR camera, and a specially developed C-mount adaptor offers a further option for connecting a camera.
The Alpy 600 spectrograph consists of a grating prism, i.e. a combination of a prism and an optical grating with 600 lines per millimetre.
