Laser Spectrometer

This is an advanced deluxe spectrometer of size 7" spectrometer, we have made arrangement for Diode laser&detectorinstead of telescope & collimator. The diode laser is held in support rigidly &in perfect alinement at the place of the collimator. similarly, the output detector is held in support rigidly& in perfect alinement at the place of the telescope. Vertical adjusting screws to aline the diode laser & detector. Supply with grating holder, grating, diode laser with power supply, and output detector with a digital meter.

A basic instrument for performing spectroscopy experiments, designed to give best possible results, mounted on stable cast iron base, protracted scale 150mm is divided on precision machine, vernier reading 1 min., telescope is fitted with 25mm dia. and 178mm focal length achromatic objective, 10x Ramsden eye piece and cross line graticule, collimeter has an adjustable precision slit of 6mm long jaws of non rusting metal, 8cm dia. prism/grating table is adjustable and has engraved ring pattern.


Supplied in a beautiful plywood box with prism holder and grating holder

The two detectors are used to measure sample and reference, respectively and simultaneously for optimizing measurement accuracy.

Lamp selection enables conserving the life of D2 tungsten lamp. Real-time clock for date time stamping of results.

Light Path Design : Double Beam

LMSPUV1900 double lightt design can prevent circuit fluctuation and stray light to ensure stability of the instrument.

LONG PATH LIGHT DESIGN

LMSPUV1900 unique 520mm long light path design greatly improved resolution and the bandwidth can reach 0.5nm.

16MM OPTICAL BASE
LMSPUV1900 series use a rigid 16mm diecast aluminum base as their optical mount to ensure the stability and reliablity.
