Are designed to meet the requirements of Research, Colleges, Schools and Industrial laboratories. They are used for accurate measurement of the diameters of different objects. They are also used in Physics Laboratories for more accurate determination of small variation in the liquid levels, Manometers, the refractive index of liquids as well as in surface tension & viscosity experiments.
The travelling microscope consists of a cast iron base with machined vee-top surface & is fitted with three levelling screws, one being fixed. The microscope can travel Horizontally 22 cm & vertically 15 ems. with the help of slides. Two slow motion knobs are provided for taking accurate readings. Vernier readings 0.01 mm. or 0.02 mm. Microscope tube consists of eyepiece 10x with 15 mm. or 75 mm. Objective. For placing objects on horizontal stage, made of milky cenolite sheet is provided on the base.

Having movement horizontally and vertically with stainless steel scale and vernier reading to 0.01 mm. or 0.02 mm.

A complete and light weight direct vision spectroscope without wavelength scale, for observing visible radiations from 400 to 750 mm.

Prod ID: BDV-1

A compact visible spectrometer which allows the direct reading of spectral length and employs a prism for dispersion. It is also useful for flame test of basic radicals.

Prod ID: BDV-2

Is a precision shop instrument. The light source is adjustable on a swivel. The retiele can be focussed moving the eye piece lens up or down. The object is focussed by rack& pinion movement is inexpensive substitute for Tool Maker's Microscope & are used where conventional tools like micrometer, dial gauges a ineffective. The measurements can be done with the microscope. The Microscope are available in 40x, 60x & 1 00x magnifications.
