The ASD LabSpec 4 Standard-Res is powered directly from a standard AC connection or optionally with a portable lead-acid gel cell battery that is shipped standard with every instrument. Fiber optic cables are removable for interchangeability and easy transport.

ASD LabSpec 4 Standard-Res i lab analyzer

The ASD LabSpec 4 Standard-Res i model includes an internal broad-spectrum halogen light source that eliminates the need for an external fiber optic light source. External fiber optic light sources, such as the Fiber Optic Illuminator, work with bifurcated probes and accessories to provide additional customized sampling options.

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)


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

Fiber Optic Illuminator

The Fiber Optic Illuminator is a portable, external light source designed for use with ASD instruments and sampling accessories that do not have a built-in light source.

Technical Specifications

Length   11.43 cm (4.5 inches)
Width   8.255 cm (3.25 inches)
Weight   292 grams (10.3 ounces)

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.


The ASD Muglight is designed for analysis of raw materials requiring reflectance and absorbance measurements. It can measure samples through glass vials, or using the ASD sampling tray adapter. It's unique and innovative design minimizes measurement errors associated with stray light and specular reflected components.

For users requiring higher intensity illumination, ASD also offers the Hi-Brite Muglight.

Rapid Analysis Probe

The Rapid Analysis Probe is specifically designed for speedy spectral collection of powders and other fine-grained materials such as small uniform seeds and grains. Its beveled tip and metal jacket greatly speed up the spectral collection process of fine grained materials to optimize workflow. Simply insert the Rapid Analysis Probe into your fine-grained media, collect the spectrum, use a chemical wipe to swipe the probe clean and move on to the next sample. It’s that easy! The Rapid Analysis Probe comes with a gimbaled white reference for high performance calibration. It can be used for quantitative predictive models.

If using this probe with a spectrometer such as a TerraSpec mineral analyzer or a LabSpec lab analyzer without an integrated light source, a Fiber Optic Illuminator is necessary. The Fiber Optic Illuminator provides the light source needed for sample collection.

Technical Specifications

Length: 21.6 cm (8.5 inches)
Spot size: 4 mm

Small Diameter Reflectance Probe

With an approximate spot size of only 2 mm, the Small Diameter Reflectance Probe was designed to collect spectra from individual small materials such as individual grains or vugs in a hand sample or rock core. It’s perfect for determining specific mineralogy of individual grains.

If using a spectrometer such as a TerraSpec mineral analyzer or a LabSpec lab analyzer without an integrated light source, a Fiber Optic Illuminator is required. The Fiber Optic Illuminator provides the necessary light source for sample collection.

Technical Specifications

Length: 10.2 cm (4 inches)
Field of View: 1 mm
