Sampling Optics
Ocean Optics offers numerous spectroscopic accessories. A short description for each accessory featured in this
manual is listed below.
" The 74-UV and 74-VIS C OLLIMATING L ENSES screw onto the end of
SMA-terminated optical fibers and other sampling optics to convert
divergent beams of radiation (light) into a parallel beam.
" The 74-90-UV R IGHT A NGLE R EFLECTOR for collimating lenses has a
mirror located under its cap that reflects light from the collimating lens
to 90°. The 74-90-UV is a 3/8-24 threaded black anodized aluminum
assembly for mounting our collimating lenses at right angles, and is
useful for applications that involve limited space and inconvenient optical
fiber routing.
" The 74-OPM O PTICAL P OST M OUNT is a 3/8-24 threaded black anodized aluminum
assembly used for mounting collimating lenses on breadboard laboratory tables, rail
carriers and other bench plates.
" The 74-ACH A DJUSTABLE C OLLIMATING L ENS H OLDER is a versatile assembly for
mounting lenses at multiple positions, and is especially useful for large or thick
samples not easily accommodated by other sampling optics such as our FHS-UV
and FHS-VIS In-line Filter Holders.
" The FVA-UV F IBER O PTIC V ARIABLE A TTENUATOR is an opto-mechanical device
that controls the amount of light being transmitted by a fiber and the amount of light
entering the optical bench of the spectrometer. The attenuator can be used for
applications where more light reaches the spectrometer than likely can be digitized
successfully by the spectrometer's high-sensitivity linear CCD-array detector. The
FVA-UV attenuates light uniformly at all wavelengths.
" The WS-1 D IFFUSE R EFLECTANCE S TANDARD is a compact physical standard for use in performing reference
measurements for diffuse reflectance applications, especially color analysis. The reflectance material in the
WS-1 is Spectralon, a substance that provides a nearly 100% diffuse reflective surface.
" The ISP-REF I NTEGRATING S PHERE is an illuminated inte-
grating sphere that couples via optical fiber to our spectrometers
to measure reflectance or emission. The ISP-REF has a transfer
optic assembly for restricting the fiber viewing angle, a 0.4"
aperture sample port, and a built-in tungsten light source.
" The FOIS-1 F IBER O PTIC I NTEGRATING S PHERE was designed
for emission experiments -- such as measuring the spectral
properties of LEDs and other light sources. The FOIS-1
consists of a 1.5" Spectralon sphere encased in an aluminum
housing, with a 0.375" input port that accepts light energy from
200-1100 nm and an SMA connector for coupling to the
spectrometer. The FOIS-1 also has threads for mounting the unit
in a variety of configurations.
