Spectrometers
for Color Measurement
The most commonly used instrument for the measurement of
the optical performance of filters, films, and optical components
is a spectrometer. Easily measure %Transmission, Optical
Density (OD), Absorbance, and Reflectance of just about
any optical element for purposes of R&D, quality control,
production, or simply to better understand your system.
Using
a StellarNet fiber optic spectrometer coupled to a reflectance
probe and fiber optic light source, it is possible to measure
film thickness by detecting the sinusoidal fringe pattern
from the samples specular reflectance. Choose between various
StellarNet spectrometers to suite your Thin Film and/or
optical measurement requirement. StellarNet offers model
spectrometers that range from 190-2300nm. Dual channel configurations,
extended range detectors, or high resolution optics can
be employed to suite your optical measurement. See the StellarNet
Thin Film Companion Software Page to learn more about film
thickness measurements.

A fiber
optic sample probe is powered with a fiber optic light source
– SL1 tungsten krypton bulb (see other options below).
For measuring the color of solid samples, an integrating
sphere, such as the IC2, is used in place of the fiber optic
reflectance probe to improve measurement consistency. The
IC2 also acts as a cosine receptor to improve irradiance
measurements. A white reflectance standard, such as the
RS50 also listed below, is required to generate a reference
for subsequent measurement of solid samples. For more information
on color applications, refer to the section entitled ”
Color Measurement Systems”.

TXF-4
includes two collimating lenses which allows the sample
to be oriented vertically as shown above. The standard fixture
allows a variable pathlength from 0 to 7cm. Custom posts can
be designed to increase pathlength. Interchangeable parts
allow the TXF-4 to be easily converted into the RPH-3 using
the same base and stand.
TXF-IC2
Vertical transmission fixture with variable path length, includes
1 collimating lens and 1 miniature 2'' integrating sphere
with 5/8'' port.Tfx-IC The integrating sphere collector is
useful when measuring the transmission of thick samples such
as bulletproof glass or samples with curved surfaces such
as lenses.

The RPH
Reflectance Probe has 6 illuminating fibers and 1 read
fiber bundled together. As an option, the 2R probe has 5 illuminating
fibers and 2 read fibers. Fibers are offered in 400µm
and 600µm diameters. The RS50 is a 50mm diameter white
reflectance standard made of Halon. It is used to take reference
measurements using the R400 Reflectance Probe. The white standard
will reflect >97% of the light from 300-1700nm.
