TM‑8CL Contact Lens Transmittance Tester/Spectral transmittance Test is an optical instrument specially designed for transmittance measurement of contact lenses. It features fast measurement speed and user‑friendly operation, complying with multiple domestic and international standards.

Function:

Transmittance Curve Graph: Displays transmittance distribution curve (280‑780 nm).

Graph Graticule: Shows vertical and horizontal graticule lines.

Quick Transmittance Comparison: Vertical graticule displays corresponding transmittance at current wavelength.

Data Analysis: Stores, recalls and compares data for Lens 1, Lens 2, Lens 3; calculates transmittance difference ^p% 

Sampling Interval: Configurable wavelength sampling interval: 1 nm or 5 nm.

Sample & Test Information: Input of test institution and sample information.

Test Report: Save, preview or print test reports in PDF (contact‑lens function optional).

Data Storage: Archive and recall raw transmittance data in TXT format.

Contact Lens Measurement:  Saline compensation via refractive index.

RGP Measurement: Supports direct air testing for RGP lenses.

Color Measurement: CE color coordinates (XY), Lab color space, E color difference.

Fast measurement speed at 1 second

Support comparison of transmittance among samples

Compare lens transmittance test among lens 1, lens 2, and lens 3 or compare transmittance at multiple postions of the same lens

Comply with International Standard

It fully comply with ISO/ GB/ EN/ANSI/AS/ NZS standard
