ASD HandHeld 2: Hand-held VNIR Spectroradiometer

The ASD FieldSpec® HandHeld 2 hand-held spectroradiometer is the low-cost, easy to use, visible-near infrared (VNIR) alternative to the full-range ASD FieldSpec 4 product line. The ASD Handheld 2 is a versatile and durable hand-held spectroradiometer that utilizes the ASD FieldSpec 4 VNIR spectrometer for accurate analysis in the 325 – 1075 nm spectral range.

Probes and Lighting

Contact Probe

The ASD Contact Probe is designed for contact measurements of solid raw materials such as minerals, grains, other granular materials. Its innovative optical design minimizes measurement errors associated with stray light and allows for measurement of samples through clear and transparent plastic bags.

In addition to the standard contact probe, ASD also offer the Hi-Brite contact probe and the Plant Probe.

All contact probes are available with a ruggedized cable feed and cable, designed for applications that involve extra cold or harsh temperatures. (see image below specifications)

Specifications:

Length10" ( 25.4 cm)
Weight1.5 lbs (.7 kg)
Power requirements12-18 VDC, 6.5 W
Lightsource type/Life (approx.)Halogen bulb/1500 hours
Halogen bulb color temperature2900 K
Spot size10 mm

Hi-Brite Contact Probe

The same design, features, and benefits of ASD's standard contact probe, but with a higher intensity illumination setting on the sample window. This higher intensity illumination is ideal for inorganic applications, and is recommended for mineral and ore characterization in mining exploration and research applications using the TerraSpecFieldSpec 4 Hi-Res and LabSpec Hi-Res spectrometers.

Plant Probe

The same great design and functionality as ASD's standard contact probe with a lower intensity bulb position for non-destructive data collection from live vegetation and other heat-sensitive targets.

The plant probe can be used alone or in combination with a Leaf Clip to protect sensitive plants.

Leaf Clip

ASD's Leaf Clip assembly is designed specifically for use with the Plant Probe to simplify the process of collecting spectra on live vegetation. The unique design includes a gentle trigger lock/release gripping system for holding the target sample in place without removing the leaf from its habitat, or inflicting damage.

Integrating Sphere

Integrating spheres collect reflected light from samples over a full hemisphere. The sphere, by nature of its internal diffuse (lambertian) reflection and integration of the energy, is insensitive to directional reflectance features coming from the sample, and therefore, gives a very repeatable “averaged” response to the reflectance of the sample placed in the beam at the sphere port. Sample placement and incidence beam/collection alignment are less critical to the measurement results because the integrating sphere looks at representative averaged energy from all angles at the same time.

General Accessories

Pistol Grips

ASD offers multiple pistol grip options for superior ease-of-use and adaptability to a variety of environmental and situational elements, when using your FieldSpec® and FieldSpec HandHeld instruments. All pistol grip designs include the quick-connect/disconnect fiber optic cable snap-in feature, pistol grip clip assembly for safely and securely affixing the pistol grip to your waist-belt on the back pack, and many offer a built-in bulls-eye level for added precision.

Fore Optics

Equatorial mount

The Equatorial Mount is used to maintain the orientation of the Direct Irradiance Attachment (sold separately) and the Full Sky Irradiance RCR (sold separately) relative to the sun.

Once the mount is manually aligned with the Earth's rotational axis and proper solar alignment is obtained using the directional keypad, this mount scans in synchronization with the motion of the sun through the sky.

The mount is powered by a rechargeable 12 volt gel cell battery pack included with the mount. The heavy duty tripod on which the mount is installed is also included. The FieldSpec® spectrometer is mounted on a tripod (available separately). The tripod tray is not a standard item.

For use with all FieldSpec® and HandHeld models.

Reference Panels

Reference Panels

ASD carries a wide array of calibrated and non-calibrated diffuse white and gray reference panels in varying sizes (from 2 x 2 in. to 12 x 12 in. or 5.1 x 5.1 cm to 30.5 cm x 30.5 cm) and reflectance levels, including encapsulated gray scale (NIST/NRC traceable) wavelength and USP standards for USP 1119. Calibrated panels come with certificate and documentation showing standard deviation and reflectance factors.

All reference panels and standards may be purchased separately. To provide our customers with a more cost-effective approach, specific sizes or styles of reference panels are included in accessory bundles designed for maximum compatibility with a particular application.

Your ASD sales representative will be able to advise you on the best option(s) for your needs.
