The transmission measurement adapter TRA100 permits determination of the spectral transmission properties of widely ranging materials under normal light incidence. Typical applications include the characterization of optical filters and glasses.

Features:

• transmission measurements at 0° incidence
• optional integrated halogen lamp or fiber connector for external light source
• wavelength range 380 - 2200nm or 200 - 2200nm, respectively
• sample size: 4 cm x 4 cm x 6 cm (H x W x D)
• measurement area approx. 1 cm across

The TRA100 is compatible with all Instrument Systems spectrometers. Coupling of the transmitted light into the spectrometer is accomplished via a multimode fiber and SMA connector, or with a fiber bundle. Additionally, two options are available for the choice of light source - a compact 10W halogen lamp fixed to the adapter or a fiber connector for use with a light source from the LS100 / LS500 series manufactured by Instrument Systems.  

Model	Light Source	Fiber Connector	Spectral range
TRA100-210	integrated halogen lamp	SMA connector	380 - 2200 nm
TRA100-211	integrated halogen lamp	for fiber bundles	380 - 2200 nm
TRA100-310	external connector for multi-mode fiber	SMA connector	200 - 2200 nm
TRA100-311	external connector for fiber bundle	for fiber bundles	200 - 2200 nm

When configured for an external light source, utilization of the full spectral range from 200 - 2200 nm is only possible with the use of an appropriate lamp (e.g. LS 500 with deuterium- und halogen lamp).
