Quick check of transmittance with specific wavelength by a bandpass filter
The TLV-305-BP is a compact transmittance meter.
This unit quickly measures the transmittance with specific wavelength by a bandpass filter.
It allows easy measurement by placing a sample after one-touch calibration.
It is suitable for a quick inspection process to conduct large volume of measurements.
Stable measurement is achieved by separating a measurement light from an ambient light with pulse operation of the white LED.
It is possible to calibrate and get the transmission data by PC via RS485.
Specific measurement wavelength is selectable
by a bandpass filter.
CWL: 440-730nm / FWHM: 10nm / Size: 25mm dia.
The additional filter holder makes it easier to
exchange bandpass filters.
