Fully Automatic Microscopic Transmission/Reflection Measurement Instrument
Sunny large microscope stand with an 8-megapixel camera and automatic xy stage. Resolution is 1um, effective motorized measurement area 70mm*70mm, and measured spot size under a 50× objective is 4 micrometers. Demonstrated leaf reflectance measurement, 350-1000nm spectral range, software-controlled automatic microscale scanning and hyperspectral capability. Introduction: Full-spectrum measurement across 380nm~950nm combines microscopy and motorized stages for fast, fine-resolution visible-band measurements. It measures small regions and curved-surface reflectance unavailable to ordinary spectrophotometers, suiting optics and miniature electronics. One instrument measures reflectance, transmittance and film thickness. Reflectance: Objective-focused Φ17~70μm spots. Film thickness: Reflectance data determine single-/multilayer thickness from about 50nm to about 100μm. Transmittance: Ø2mm parallel illumination through the stage measures planar samples. High speed: A plane grating and line sensor measure all wavelengths simultaneously.
