Spectrograph, High spatial and spectral resolution

Manufacturer's part number :

IsoPlane® SCT 320

Manufacturer Princeton


Description :

The IsoPlane™ SCT 320 spectrograph combines extraordinary imaging with outstanding spectral performance. The IsoPlane SCT-320 Schmidt-Czerny-Turner spectrograph overcomes the limitations of traditional Czerny-Turner (CT) instruments by eliminating astigmatism and greatly reducing. Large-diameter optics and interchangeable triple-grating turrets permit operation from the UV to Mid-IR even at low light levels and a variety of spectral resolutions.
