Portable UV-VIS-NIR-SWIR Spectroradiometers PSR+3500 Spectral Evolution

Our field portable, remote sensing units offer the following advanced features :

100% linear photodiode array platform- with InGaAs and silicon detectors for best resolution and sensitivity @ 350-2500nm ranges

Fast, full spectrum UV-VIS-NIR measurements with one-touch operation- autoexposure & auto dark current shutter

Diffraction grating / beam splitter optics- no moving gratings or trifurcated fiber optics to break in the field

No internal fiber optics- allows maximum sensitivity and S/N ratio with higher performance direct FOV lens optics

Industry standard optional SMA fiber optic connection for easy interchangeability

Lightweight ( <7 lbs with slide-in LiIon rechargeable battery ) and easy to carry

Bluetooth interface for wireless operation

Features unique to SPECTRAL EVOLUTION Portables include :

Li-Ion slide-in rechargeable batteries ( 2 provided ) with separate external charger for continuous, uninterrupted use

Software for both Windows-based laptops and bluetooth-compatible personal digital assistant (PDA) for maximum flexibility

Membrane control panel for stand-alone operation without a computer (includes flash memory to hold 1000 scans)

Snap-on battery-operated cooling fan option for stable performance in extreme high-temperature conditions

Nylon carrying strap with sturdy, reinforced eyelets for added security

Laser guide to aid in target sighting with foreoptics (spectroradiometers only)

Tripod mounting holes
