Ibsen Photonics has released an improved version of its ultra-compact PEBBLE VIS OEM spectrometer. The new PEBBLE VIS combines an ultra-compact form factor of only 20 × 15 × 8 mm with high resolution and sensitivity as well as environmental ruggedness. The wavelength range has been shifted towards the UV to cover 360–830 nm, and the resolution is still 6 nm. The pure transmission-based optics inside PEBBLE provide high sensitivity, low stray light and thermal stability. The detector is a CMOS array with 256 pixels, and the electronics interface is a tiny flex-connector that fits on the new miniature DISB-105 read-out electronics.
