Spectrometers


eppboth.jpg (45946 bytes) The EPP2000 portable spectrometers are rugged.  You can drop'em, kick'em and love'em.  They don't require an expensive A2D card. It's already taken care of when you connect the digital cable to the printer port on your portable notebook or PC.  Need the printer too? Plug a second printer port into your PCMCIA or PC bus slot!

EPP2000 portable or ISA2000 plug-in Spectrometer models:

UV...............range 200-600nm    *r1
UV2.............range 200-400nm    *r4
VIS..............range 350-1150nm  *r2
NIR..............range 500-1200nm  *r2
NIR2............range 600-1000nm  *r1
NIR3............range 550- 840nm   *r3
XNIR...........range 600-1400nm  *r2
XNIR2.........range 1200-1600nm *r1

plus!

EPP2000C model for UV+VIS range 200-850nm (aberration corrected optics and no mirrors)

slit size     resolution *r1   resolution *r2   resolution *r3   resolution *r4
10um       0.5nm                  1.1nm
25um       1.2nm                  2.5nm            0.35nm             0.25nm
100um     5.0nm                10.0nm

Up to 8 units can be attached on a single cable in any combination of optical configurations.
All units can request scans at the same time.  Each unit has its own A2D and 2050 wavelength scan memory.  This allows development of "synoptic" multi-channel applications. Detectors are soldered onto small circuit cards which are then mounted to the spectrographs using locking hardware (see pictures below).  This reduces the risk of alignment problems caused by vibration in shipping or field portable operations and eliminates thermal instability for the detector mount.

The EPP2000C is the perfect choice for UV+VIS process control because it has excellent stability over a wide temperature range without requiring active temperature compensation.   There are less parts that can move and less parts that could fail.  The concave grating is holographic which reduces stray light, and is aberration corrected providing the best possible spectra.  The system resolution is 0.7nm across its range from 200-850nm.

The EPP2000 spectrograph uses the same electronics card and cable as the EPP2000C and is about one third the size.  This combination of size and performance makes a great choice for OEM applications.  Custom optic configurations are available upon request.   Detachable optics allow flexibility for field maintenance and logistics.

ISA2000
  - This is a PC plug-in spectrometer on a card.  It has the same detector and optic configurations available for it as the EPP2000 shown above.  This is a great choice for OEM and application integrators. Detachable optics allow flexibility for field maintenance and logistics.

Up to 16 units can be installed in a single industrial computer.  All units can request scans at the same time.  Each unit has its own A2D and 2050 wavelength memory.
