Fiber Optic Field Spectroradiometer is built for remote sensing.

Press Release Summary:

Sealed to resist dust/dirt/moisture ingress, portable RS-3500 does not require sample prep and enables in-field, non-destructive data collection. NIR field spectrometer (350–2,500 nm) offers respective resolutions of 3, 8, and 6 nm at 700, 1,500, and 2,100 nm. Designed without any moving optical parts, rugged 7 lb unit features quick optical connect/disconnect for in-field accessory swapping, leaf clip with external data triggers and disposable white reference, and ILM-105 light source.

Original Press Release:

Spectral Evolution's RS-3500 Enhanced Full Range, Fiber Optic Field Spectroradiometer Built for Remote Sensing.

Lawrence, MA – The SPECTRAL EVOLUTION RS-3500 field portable spectroradiometer for remote sensing meets the needs of a wide range of remote sensing applications, and delivers the following benefits:

• Fast – rapid collection of quality data in the field

• Non-destructive – the sample remains unharmed by the measurement

• Easy – no sample prep – you get data without delay

What makes the RS-3500 a rugged field unit for remote sensing?

• Lightweight – only 7 lbs.

• No moving optical parts, sealed unit resists dust, dirt and moisture, stainless steel jacketed fiber optic cable – all make this one tough field spectrometer

• Quick optical connect/disconnect so you can swap accessories like the contact probe, leaf clip and pistol grip in the field

• Thumbscrew fiber optic cable mount for quick removal and improved repeatability

• New leaf clip with trigger and disposable white reference

• New ILM-105 light source – rail mounted to the unit

• External data collection triggers on the leaf clip and contact probe are ideal for single-user operation

• GETAC field PDA  for controlling the instrument, collecting and viewing scans, GPS, voice notes, digital pictures – all tagged to your spectra saved as an ASCII file

The RS-3500 provides autoshutter, autoexposure, and autodark correction before each new scan, with no optimization step, for one touch scanning. With no moving optics, it delivers superior field reliability.

The RS-3500 delivers the highest resolution and greatest sensitivity available in a field spectrometer for remote sensing. It provides fast, accurate analysis in situ for:

• Ground truthing hyperspectral images

• Chlorophyll and moisture analysis to identify healthy and stressed vegetation

• Agricultural analysis to prevent over/under fertilization

• Forest canopy studies

• Plant species identification

• Crop health including photosynthesis efficiency

• Soil analysis for moisture and nutrients

• Total carbon, organic carbon and hydrocarbon in soil studies

• Topsoil fertility and erosion risks

• Soil mapping and monitoring

The RS-3500 features:

• Full range NIR field spectrometer – 350-2500nm

• High resolution

- 3nm @ 700nm

- 8nm @ 1500nm

- 6nm @ 2100nm

• High sensitivity (low noise equivalence radiance)

• A range of accessories including contact probe, pistol grip, leaf clip, FOV lenses and more
