ImSpector V10 vs. ImSpector V10E

Specim offers two VNIR spectrograph models for ultimate flexibility and customization.

The ImSpector V10 is the standard series VNIR spectrograph developed by Specim. It offers smaller sensor compatibility, combined with compact size and an affordable price point. Fore optics options include OL8, OL12, OL17, OL23 and OL35 lenses for 2/3" or smaller detectors.

The ImSpector V10E is Specim's enhanced series VNIR spectrograph. It features a built-in mechanical shutter and 30 µm slit delivering enhanced spectral and spatial resolution, reduced aberrations and lower Smile and Keystone. Fore optics options include OLEWIDE, OLE18.5, and OLE23 for 2/3" or larger detectors.

Specim V10/V10E Key Benefits:

Detector flexibility
Higher spectral resolution (V10E)
Enables integration into specialized setups
Cost efficiency
