Portable Light Transmission Meter
The KVLM-A is a portable spectrophotometer designed for in situ measurement of transmission in the visible
wavelength range (luminous transmission). Its hand-held design and compact size allow measurement at the
test sample without any size limitations. Profiling a test sample by multiple measurements across the sample
is easily performed. The instrument can also be integrated into stationary measurement set-ups.
The KVLM-A offers 2 different light source options :
◆ CIE Standard Illuminant A
◆ CIE Standard Illuminant D65
By integrating these 2 light source options, the KVLM-A is suitable for use in:
◆ process control
◆ incoming inspection as well asin research and development for measurement of the efficiency of
◆ influence of interference effectsto transparency
◆ legal conformity of window transmission (ECE R43)
◆ any spectrophotometer application in the visible wavelength range where mobility or compactsize isrequired.
Using a internal targeting camera, the KVLM-A is one of the easiest to operate fully portable spectrophoto-
meters, and ca even be used on 3D formed samples where the perpendicular alignment is critical.
The automatic ambient light compensation feature uses LED pulse modulation technology to suppress
ambient light pollution, and at the same time extending battery life.
KVLM-A also has a built in memory to store up to 100 measurements, and the software provided can be used
to monitor the measurements in real time, or to backup and store the results for further manipulation..
