Abstract

Overview

ISO 13697:2006 - Optics and photonics - Lasers and laser-related equipment - Test methods for specular reflectance and regular transmittance of optical laser components - specifies high-precision measurement procedures for determining specular reflectance and regular transmittance of laser optical components. The standard provides laboratory test arrangements and calibration routines whose accuracy exceeds the procedures in ISO 15368 by several orders of magnitude, making it suitable for demanding laser and photonics applications.

Key topics and requirements

Measurement principles: Optical determination of reflectance/transmittance as the ratio of regularly reflected/ transmitted power to incident power. Procedures cover near-normal incidence and angular dependence (double-bounce arrangements).
Test arrangements: Use of an integrating sphere, a highly reflective chopper mirror that splits the beam into probe and reference paths, and an additional calibrated mirror for transmittance/angle measurements.
Calibration: Two-step calibration to determine chopper and reference mirror reflectances (measurements with known mirrors and power ratios). Calibration is essential for traceable, high-accuracy results.
Laser beam preparation: Spatial filtering (beam-transforming optics), imaging of the laser out-coupling window onto the sphere port, and attention to beam diameter, divergence and point stability. Special consideration is given to longer wavelengths (e.g., 10.6 μm).
Signal detection: Use of lock-in techniques synchronized to the chopper frequency to detect very small power differences; detector noise, relative intensity noise and chopper frequency selection affect detection limits.
Environmental and sample handling: Tests in dust-free filtered air,
