TM-8S is advanced optical measurement instrument designed for measuring the transmission ratio of the lens. It enjoys fast speed and high accurate measurement, meeting all kinds of standards both home and aboard.

Features:

Capable of measuring the lens with refractive power

Supports a wide range of sample for testing

Compliance with International standard

Fast speed at 1 second per measurement

Easy to use

Fast speed at 1 second per measurement

Support sample comparison in terms of transmittance

It allows user to compare transmittance data among three lens, or compare transimttance data of different testing positions on the same lens

In below photo, red, blue and green icon represent three kinds of sample for comparision

Transmittance Curve for Three Different Type of Samples

Support a wide range of samples for testing

Compliance with International Standard

Detailed Report:

Function:

Transmission Curve: Shows transmission distribution curve (280 ~ 780 nm)

Chart graduation lines: display vertical and horizontal lines - lens transmittance difference  Δp%

Sampling interval:  sampling can be set at 1nm or 5nm wavelength interval

Sample testing information: sample information entry

Test report: Test report PDF directly save, preview and print (optional for contact lens)

Data saving: transmission data archived in TXT format, easy to trace.

Polarization Testing: Without adjusting angle, you can obtain polarization averages directly (air calibration)

Polarization efficiency P% test: transmittance at maximum and minimum polarization direction (polarizer calibration)

Color test: CIE color coordinate (XY), Lab color, E color difference
