The Ophir 4061 is a fan-cooled thermal sensor head engineered for precise laser power and energy measurement across ultraviolet, visible, and infrared wavelengths. It delivers continuous power monitoring from 100 mW to 250 W and pulse energy measurement from 50 mJ to 300 J, making it suitable for both CW and pulsed laser systems. The sensor features a spectrally flat broadband absorber optimized for uniform response across its measurement range.
