Broadband White Light Source
Affordable broadband white light for visible optical spectroscopy
Output light over the wavelength range 360 nm - 900 nm
The Ossila Broadband White Light Source is a USB-C powered LED device that outputs light over the wavelength range 360 nm - 900 nm. Ultraviolet and blue LEDs are combined on a single die, and coated with phosphors with emission extending into the near infrared. This single light source allows optical spectroscopy measurements over the entire visible range.
Designed for use with the Ossila Optical Spectrometer and our range of optical spectroscopy equipment and accessories, the broadband white light source can be used in free space arrangement or connected to a transmission holder or cuvette holder with an optical fiber. It can also be bolted to any standard metric or imperial optical table or optical breadboard plate.
