If you want to remove grating on a Lhires III, it is very simple. This will change the configuration for the resolution of the project.

Transform your LISA slit from Visible to near-Infra-Red (650-1000nm) domain.Be careful: this operation takes time and requires very precise handling

12V/7A regulated power supply with a 4-way power cable

This mounting kit works for the Star Analyser 200 and other 1.25" filter cells. Plates can be easily trimmed to size with scissors.

Adapter to use a C-mount camera on an Alpy 600 spectrograph

This 3.8° prism placed in front of your Star Analyser does improve resolution by 20%.

Optical fiber connector (FC standard) for Alpy spectroscope

Grating and its support are very easy to remove on a Lhires III. This allow to change in few seconds your configuration: adapt it to the resolution you need for your project!

This automatic calibration module is a perfect addition to your LISA spectrograph, specially if you plan remote observations. It includes Neon and Tungsten lamps for wavelength calibration and flat processing

Barlow element for Alpy 600 spectrograph

Alpy guiding module is the key element to use your Alpy 600 spectrograph on the stars.

We propose in option a M42-31.75mm (also called M42-1.25") adapter which allow you to mount the Star Analyser 100 on a SLR (digital or not) equipped with a T/T2 ring; then to mount it on a standard 1.25" eyepiece holder.

This M42x0.75 / C-mount adapter is used with classical CCD camera with M42 thread - such as Atik Titan for exemple.
