The core performance of optical films, filters, coated glass, semiconductor wafers, flexible optical materials, and protective transparent materials mainly depends on the three basic parameters of spectral transmission, reflection, and absorption. These three parameters mutually confirm each other and are indispensable, serving as the core basis for determining the optical loss, band selectivity, coating uniformity, and optical compatibility of the materials. Traditional testing equipment has a single function and can only measure transmission or a single reflection parameter separately, making it impossible to calibrate the data in a linked manner. At the same time, there are problems such as large stray light interference, poor weak signal acquisition, low data repeatability, and limited angle adaptation, which make it difficult to meet the requirements of high-precision optical material selection, coating process iteration, device quality calibration, and mass production quality control, greatly restricting the efficiency of the development and implementation of optical materials and optoelectronic devices.
Based on the mature integral sphere optical design, high-precision spectral detection, and intelligent calibration technology, Saifan Optoelectronics has launched a transmission, reflection, and absorption spectral testing system. Integrating the three core testing functions into one, relying on the precise measurement light optical path and algorithm linkage, it can simultaneously and accurately test transmittance, reflectance, and absorbance/density. With wide spectral coverage, ultra-low error, non-destructive testing, and intelligent analysis, it completes the full-spectrum characterization of various optical materials in one step, providing a standardized, traceable, and high-precision complete testing solution for scientific research experiments, process optimization, industrial quality inspection, and providing a complete testing solution for high-precision optical material selection, coating process iteration, device quality calibration, and mass production quality control.
Three-parameter integration and linkage testing, saying goodbye to the drawbacks of equipment split testing
Different from the limitations of traditional single-function testing equipment, this system realizes integrated testing of transmission, reflection, and absorption spectra, without the need to replace the optical path, modify the sample, or repeat alignment, and can quickly complete the synchronous collection and linkage calibration of the three core optical parameters. Based on the energy conservation algorithm, it automatically converts transmission rate, reflectance, and absorption rate data, with parameters mutually confirming and data closed-loop traceability, completely avoiding system errors and sample secondary displacement errors caused by multiple equipment testing, significantly improving testing accuracy and experimental efficiency.
The system can accurately output full-band spectral transmission curves, reflection spectral curves, and absorption spectral curves, simultaneously calculating average transmittance, optical density, optical loss, and band cutoff characteristics, accurately reflecting the coating quality, doping characteristics, structural defects, and optical loss laws of the materials, perfectly adapting to core scenarios such as optical material basic characterization, device performance calibration, process benchmark analysis, and other scenarios.
Wide-spectrum high-precision spectral division, suitable for all types of optical samples
The system is equipped with a deuterium lamp-halogen tungsten lamp composite wide-spectrum light source and a high-precision spectral architecture, achieving a wide ultraviolet-visible-near-infrared ultra-wide wavelength coverage of 200nm–2500nm, fully adapting to the testing of various forms of optical samples. Whether it is hard optical glass, precision filters, optical coated components, semiconductor wafers, or flexible films, coating materials, transparent protective materials, powder optical media, all can be accurately tested without discrimination, covering the mainstream optical characterization wavelengths in the scientific research and industrial fields.
Based on the precise grating spectral division and detailed scanning technology, the equipment has high wavelength accuracy and excellent repeatability, and is paired with an optimized optical path noise reduction design, effectively suppressing stray light interference, eliminating spectral baseline drift, curve distortion, and data deviation problems. Facing samples with different characteristics such as high transparency, high reflection, and high absorption, it can maintain a stable signal-to-noise ratio, accurately capture subtle spectral differences, and clearly present the real optical performance characteristics of the raw materials.
The system is equipped with a high-precision integral sphere light measurement module, perfectly solving the problem of traditional direct light path unable to test diffuse transmission and diffuse reflection samples, and meeting the requirements of mirror and diffuse optical characteristic testing needs.

It is suitable for testing special samples such as frosted materials, coating films, porous optical media, and diffuse plates. It comprehensively covers the testing blind spots of conventional optical equipment.
The entire testing process adopts a non-contact non-destructive detection mode. No sample digestion is required, and no complex pre-treatment is needed. It does not damage the sample structure and performance. It can be used for repeated testing of precious samples, dynamic monitoring of processes, and screening of batch samples. It supports vertical incidence and multi-angle incidence testing. It can simulate different working conditions of light environments and also reflect the optical performance of raw materials in actual use. The test data is in line with real application scenarios.

The system automatically completes baseline correction, blank calibration, stray light elimination, data normalization processing, and does not require manual intervention throughout the process.
