Light Sources


HOLMARC offers a number of light sources for the spectral range of 200 - 2000nm which can be mounted directly to our monochromators or can be used independently. With the appropriate adapters, some of the light sources can be mounted to our monochromators along with optical chopper or filter wheel. Additional adapters and interface devices are available for focusing and launching the light directly into optical fibers.

Deuterium

Spectral Range : 200 - 400nm

Good UV lamp, generally with higher output than Xenon lamps



Xenon

Spectral Range : 200 - 2500nm

: 250 - 2500nm (Ozone free version)




Tungsten Halogen

Spectral Range : 350 - 2400nm

Continuous spectral output. More stable than Xenon lamps

Lamp Houses for Spectral Study

Sodium Vapor Lamp


A sodium vapor lamp is a gas discharge lamp that uses sodium in an excited state to produce light. The low-pressure sodium lamp has remarkably high luminous efficiency. The radiation is nearly mono-chromatic, yellow in color.


Model : HO-LH-SV35W

Model No: HO-LH-SVC

Mercury Vapor Lamp


A mercury-vapor lamp is a gas discharge lamp that uses mercury in an excited state to produce light. They offer long life time as well as intense lighting for spectral applications.


Model : HO-LH-MV100W

Multi Spectrum Tube Housing for spectral calibration


Model : HO-SP-MSTH-06


HOLMARC’s Multi Spectrum Tube Housing holds six spectrum discharge tubes simultaneously. It can quickly switch from one gas to another without handling the tubes. Power supply is common for all discharge tubes, which is kept inside the unit.

The gas tubes are permanently enclosed, which protect the tubes from breakage. Optical fiber can be directly attached to this unit for fiber optic spectrometers.

Spectrum Discharge Tube with Lamp House


Filled with spectroscopically pure gases. The following discharge tubes are available :


01 Argon 07 Oxygen
02 Neon 08 Mercury vapor
03 Krypton 09 Sulphur
04 Ammonia 10 Hydrogen
05 Carbon Dioxide 11 Helium
06 Nitrogen    

High Voltage Transformer

Continuously Variable


Model : HE-DT-PSV


Variable discharge tube power supplies are designed to be used with different gases. The discharging action is controlled by a knob and can be adjusted to get optimum performance as each gas exhibit different discharge voltages. The complete unit is enclosed in a metallic casing.
