Optical Homogenizer

Available with 60 mm × 60 mm and 120 mm × 120 mm projected fields, it is designed for applications requiring both high irradiance and high spatial uniformity. When paired with Bentham fibre-coupled monochromator and broadband-source systems, it provides highly uniform, wavelength-tuneable illumination across a broad 200 nm to 2.5 µm spectral range.

The FCH is designed to provide uniform illumination without the high optical losses normally associated with integrating-sphere based uniform sources. For applications where source power is limited, or where high irradiance is required at the measurement plane, this can be a significant advantage.
