Holmarc offers a number of light sources to cover 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 sources may be mounted to our monochromators along with an optical chopper or filter wheel. Additional adapters and interface kits are available for focusing and launching the light directly into optical fibers.
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-SV
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
Spectrum Discharge Tube with Lamp House
Model : HO-SDT-XX
Filled with spectroscopically pure gases. The following discharge tubes are available:
05 Carbon Dioxide
08 Mercury vapor
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, 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.
High Voltage Transformer
Model : HE-DT-PSV
Variable discharge tube power supplies are designed to perform with different gases. The discharging action is controlled by a variable knob and can be adjusted to get optimum performance as each gas exhibit different discharge voltages. The complete unit is mounted in a metallic casing.
