Integrated Transmittance-Reflectance Spectroscopic System

The iSpec-TR400 Microspherical Transmission-Reflection Spectrometer is a flagship product of LiSen Optics (LiSen Optics), specifically designed for full-wavelength microspherical optical component transmission-reflection measurement. Building upon the foundation of the iSpec-R Microspherical Reflectance Spectrometer, the iSpec-TR400 adds a transmission rate detection feature, enabling one instrument to simultaneously measure both reflectance and transmittance. The switch between reflectance (R) and transmittance (T) is simple and convenient, making it a comprehensive tool. It is widely used for measuring relative and absolute transmission and reflection rates of various optical components and materials, including optical mobile phone cover plates with IR holes, prisms, coated mirrors, cemented mirrors, parallel plates, solar films, filters, and other plane, spherical, and aspherical optical components and combination lenses.

Product Introduction

Instrument Features

● Spectral Range: 380~1100nm, with ultraviolet-enhanced light source.

● Supports CIE-X, Y chromaticity diagrams, and Lab* measurements.

● Professional spectral measurement software for convenient data management.

● Capable of measuring reflectance in small areas through microscopic determination, and can also perform refractive index measurements.

● Rapidly achieves R+T detection, with a single measurement time of less than 1 second and high repeat accuracy.

● Unique optical system design and specialized software algorithms allow for rapid and accurate determination of surface transmission-reflection rates without needing to blacken the back of the test components.
