Large-aperture beam profiler [25 mm / For visible light]（Large beam profiler）
LBP-B25VIS-U
The LBP-B25VIS-U is based on the fundamental performance of the LBP-B50VIS-U, a large-aperture, high-power beam profiler that is the standard model in the series. It was developed with various improvements to enable light source measurement in confined spaces. By reducing the length and width of the light-receiving surface to half the size of conventional models and improving sensitivity, it accurately captures light sources. This large beam profiler achieves higher optical resolution than the previous LBP-B50 model, enabling precise light source evaluation.
- Light receiving surface dimensions: 25 mm × 25 mm
- Optical resolution: approx. 50 μm
- Measurement wavelength range: 400 nm – 1100 nm(Focus adjusted at specified wavelength)
- Laser measurement up to high output is possible (0.1 W/cm2 to 100 W/cm2).
- With a function to reduce speckle (sparkling light and dark spots)
- Beam profiler analysis app(LaseView )included
