UV optical power meter specifications

UV optical power meters measure ultraviolet light intensity across UVA, UVB, and UVC ranges with high accuracy, repeatability, and often feature detachable probes, data logging, and digital interfaces.

Key Specifications

Wavelength Range: UV optical power meters typically cover UVA (315–400 nm), UVB (280–315 nm), and UVC (200–280 nm), with some probes calibrated for specific peaks such as 220 nm, 253.7 nm, 260 nm, 310 nm, 365 nm, 380 nm, 400 nm, 420 nm, 436 nm, and 540 nm for UVA, UVB, and UVC applications (OAI Model 308) . Power Measurement Range: Meters can measure from very low intensities, e.g., 0.1 mW/cm², up to high intensities like 1999.9 mW/cm², depending on the probe and meter configuration . Some systems include sliding neutral density filters to extend the dynamic range from 500 pW to 500 mW (Thorlabs S130C sensor) . Accuracy and Linearity: High-precision meters offer ±3% accuracy and repeatability within ±3 LSB, with linearity maintained across the full measurement range . Detachable Probes: Many UV meters feature interchangeable probes for different UV bands, allowing direct reading without additional adjustments. Probes often use ultra-stable silicon detectors with spectral shaping filters for precise response . Data Logging and Connectivity: Advanced meters provide high-speed serial ports, USB interfaces, and optional software for real-time data logging, including intensity, wavelength, time, and calibration information. Some models support remote control via PC software or Bluetooth . Display and Controls: Digital meters often include LCD or touchscreen displays, auto-ranging, peak hold functions, and programmable attenuation or calibration settings. Capacitive buttons or touchscreens allow quick access to measurement modes and zeroing functions . Power Supply: Handheld meters are typically powered by 9V batteries or external adapters, designed for low power consumption to extend operational life . Applications: UV optical power meters are widely used in photolithography, MEMS fabrication, 3D printing, UV curing, sterilization, and packaging industries . Calibration: Many meters provide NIST-traceable calibration to ensure measurement reliability and compliance with industry standards .
