HandHeld 2: Hand-held VNIR Spectroradiometer

A versatile and durable hand-held spectroradiometer  for accurate analysis in the 325 nm – 1075 nm spectral range.

Product description

It  is a versatile and durable hand-held spectroradiometer that utilizes the FieldSpec 4 VNIR spectrometer for accurate analysis in the 325 nm – 1075 nm spectral range.

The HandHeld 2 provides the ideal combination of performance, portability, and durability. It employs a high-sensitivity detector array, a low stray light grating, a built-in shutter, DriftLock dark current compensation, and second-order filtering to produce a high signal-to-noise spectrum in under a second.

Field data acquisition is streamlined with embedded remote sensing software. The results are shown on an integrated, high-visibility color display making sample collection simple, in challenging areas without the worry of carrying a computer.

The optional GPS accessory accelerates data collection, simplifies location/spectrum correlation and eliminates the need for external location record keeping. In addition, it can serve as a VNIR-only hand-held spectrometer when used with a fiber optic cable and contact probe accessories.

Hi-Brite Contact Probe:

For non-destructive contact measurements and characterization of mineral and ore samples.

Fore Optics:

Foreoptics control the field-of-view and maximize data collection to better meet specific application requirements. A wide selection of foreoptics lenses are available for use with the FieldSpec® 3 and FieldSpec® HandHeld 2 spectroradiometer systems.Ideal for analysis of grain, food, and other irregularly or non-homogeneous material samples.

Leaf Clip:

Use with ASD’s family of Contact Probes for non-destructive, one-handed functionality, and improved analysis of live vegetation and other thin heat sensitive targets

Reference Panel:

Reference panels are available in calibrated and non-calibrated diffuse white and gray, in varying sizes and reflectance levels, including encapsulated gray scale (NIST/NRC traceable) wavelength and USP standards for USP 1119.
