The SP-100F Multifunctional Spectroradiometer features a versatile “swap-and-go” design that utilizes interchangeable head attachments to allow measurement of spectral radiance, irradiance and flux. The SP-100F senses which measurement head is attached and automatically switches measurement units and calibration files, making this the most versatile, cost-effective spectroradiometer available.
Small Spot Size Attachments
The SP-100F has all of the features of our SP-100 with the additional capability of measuring small spot sizes. Users may select optical attachments that allow 3 mm, 1 mm, 0.5 mm and 0.25 mm diameter spot measurements. The small spot size optical attachments have a magnifier for the operator to look through to align the red laser spot on the spot to be measured. The image above shows a real view of the laser spot on an LCD display character as seen through the magnifying optics.
