SR-6500
The SPECTRAL EVOLUTION SR-6500 NIR spectroradiometer covers the UV/VIS/NIR range from 350-2500 nanometers. It features ultra high resolution and very stable performance with three high density thermoelectrically cooled photodiode arrays. The SR-6500 is also calibrated to NIST-traceable radiometric calibration standards.

Resolution at FWHM for the SR6500 is:
• 1.5nm @ 700nm
• 3.0nm @ 1500nm
• 3.8nm @ 2100nm

Resolution is achieved using three high density solid state thermoelectrically cooled photodiode arrays:
• 1024 element TE-cooled silicon phtotodiode array detector (VIS-NIR)
• 512 element TE-cooled InGaAs photodiode array detector (SWIR 1)
• 512 element TE-cooled extended InGaAs photodiode array detector (SWIR 2)

The SR-6500 features the following Noise Equivalence Radiance (NER) performance with a 1.5 meter fiber optic:
• 0.8 x 10-9 W/cm2/nm/sr @ 400nm
• 0.3 x 10-9 W/cm2/nm/sr @ 1500nm
• 5.8 x 10-9 W/cm2/nm/sr @ 2100nm

NER is a measure of instrument sensitivity. Other features of the SR-6500 include:
• All fixed optics – no moving parts for rugged reliability
• Auto-exposure, auto dark current shutter
• DARWin SP Data Acquisition software saves all scans as ASCII files for use with other software programs

The SR-6500 includes wireless Bluetooth and USB communications and has an operating range from 0-40°C. Physical parameters include:
• Dimensions:
12.4 x 8.7 x 4.4 inches (31.5 x 22.9 x 38.7 cm)
• Weight:
11 pounds (4.99 kg)

What kind of applications will benefit from the higher resolution?
• Mineral identification and analysis where resolution can help to distinguish between minerals with very similar spectra or to unmix and identify minerals in trace amounts.
• Soil studies for the identification of different soil characteristics, clay types, presence or absence of nutrients and moisture.
• Vegetation studies for plant stress/health, over-fertilization, species identification and more.
• Lab applications such as materials identification, etc.
• Solar radiance and irradiance research.
• Microbial diversity research

Introducing the New PSR-1100f from SPECTRAL EVOLUTION – an ideal spectrometer for vegetation studies, plant science, and more.
Looking for a spectroradiometer that you can use in the field for vegetation studies, agricultural research, crop health analysis, biomass research, studies of nitrogen levels, and more?

The newly re-designed PSR-1100f is SPECTRAL EVOLUTION’s smallest, lightest, full featured field spectroradiometer. It has a spectral range of 320-1100nm and can be used with a laptop or handheld microcomputer, or as a standalone instrument with its built-in keypad and LCD display. The PSR-1100f is well suited for remote sensing and ground truthing in a very wide range of applications. It provides a 25°, one meter fiber optic cable with an industry-standard FC connections and allows the user to select from 1,2,3,4,5,8 and 10° field of view (FOV) lenses, or connect to a handheld contact probe or our unique leaf clip.

The PSR-1100f features:
• Spectral range of 320 – 1100nm
• Rugged anodized aluminum construction for reliability in the field
• 1 meter fiber optic cable with an industry-standard FC connection
• Available with 1,2,3,4,5, 8 and 10° fiber optic lenses
• Keypad and LCD display allow for standalone operation – system stores up to 2500 scans – or use with laptop or handheld microcomputer
• Auto-exposure and auto-dark shutter for easy one-touch operation
• Snap-in lithium-ion rechargeable battery for field use
• NIST-traceable radiance calibration for 25° fiber optic cable
• DARWin SP Data Acquisition software - easy to use, stores data as ASCII files for use with third party analysis software


The PSR-1100f can be equipped with our innovative leaf clip for reflectance measurements. The leaf clip includes a built-in reflectance panel, small spot, and low power illumination. It allows you to measure a small leaf without damaging the sample. You can also attach a handheld contact probe with a comfortable pistol grip, a built-in light source, and integral power triggering cable, well-suited for measurement and analysis in the field.


With DARWin SP Data Acquisition software, researchers also have access to pull-down menus for the USGS spectral library, as well as 19 vegetation indices, including NDVI, SR, SAVI, ARVI, EVI, IPVI, PRI, WBI, PAR, and more.

Maximum illumination for sample scans with Spectral Evolution’s new companion ILM-660 light source
The SPECTRAL EVOLUTION ILM-660 light source provides maximum illumination for samples. This 100 watt tungsten halogen source is perfect for use with dark sample minerals when used with the companion SR-6500 field spectrometer and EZ-ID mineral identification software. The SR-6500 offers ultra high resolution scanning of samples and is ideal for analyzing minerals in conjunction with AVIRIS NG satellite data.

The ILM-660 includes a removable sapphire window and a glass Petri dish for holding chips or powders. The ILM-660 attaches to the spectrometer/spectroradiometer using a quick release fiber mount connection.

The ILM-660 is just the latest accessory from Spectral Evolution. Other accessories for remote sensing include:
• A wide variety of light sources including the ILM-105 5W tungsten halogen light source and the ILM-550 50W tungsten halogen spotlight
• Two reflectance contact probes with 3mm and 10mm spot sizes
• Unique leaf clip
• Benchtop reflectance probe
• Pistol grip with external trigger
• Diffusers – straight and right angle
• Range of direct attach lenses
• Range of fiber mount FOV lenses
