PC2000-UV-VIS Spectrometer
 |
The PC2000-UV-VIS Miniature Fiber Optic
Spectrometer is a low-cost, general-purpose instrument for
absorbance, reflectance and emission measurements. Unlike Ocean Optics external
spectrometers, our PC2000-UV-VIS is pre-configured with a grating,
order-sorting detector coating and entrance slit that make the
spectrometer versatile enough for a variety of applications.
The PC2000-UV-VIS has been
discontinued. It has been replaced with the
USB4000-UV-VIS Spectrometer. |
The PC2000-UV-VIS consists of a low-cost,
2048-element linear CCD-array fiber optic PC plug-in spectrometer mounted
on a half-length, 1 MHz ISA-bus A/D converter. This sturdy spectrometer-A/D
converter combination fits easily into a slot in the PC. The
PC2000-UV-VIS is pre-set to a 200-850 nm wavelength range (click
here for grating efficiency), and comes with a UV2 Detector Upgrade,
multi-bandpass order-sorting detector coating and 25 mm entrance slit for
high-resolution (to 1.5 nm FWHM) performance. Operating software is also included.
The "external" version of the
PC2000-UV-VIS is the S2000-UV-VIS,
which interfaces to the PC via an ISA-bus or PCMCIA-type A/D converter. Custom PC2000
PC Plug-in Spectrometer configurations are also available.
The light sources and sampling optics used
with the PC2000-UV-VIS are priced separately. Complete spectrophotometric
systems are available for less than $4,000.
The PC2000-UV-VIS Spectrometer features a
compact optical bench coupled to a 2048-element linear CCD-array detector.
The spectrometer accepts light energy transmitted through single-strand
optical fiber and disperses it via a fixed grating (set for 200-850 nm)
across the CCD array. An SMA 905 connector allows for easy coupling to
Ocean Optics' comprehensive line of fiber optic light sources and
accessories.
Specifications
Ocean Optics miniature fiber optic
spectrometers offer high performance at low cost, in a convenient, modular
package. Optical performance varies according to a number of factors,
including the grating's groove density and the entrance
optics' size -- as well as the application itself (for example, low vs. high
light level applications).
