All 14 lasers in the OBIS series have the industry’s most compact footprint 70 x 40 x 38 mm (2.75 x 1.57 x 1.5 in) for lasers in this power range. Standard features include flexible operation via USB, RS 232 and serial interface ports to monitor and control all laser functions.
Both new OBIS wavelengths are expected to find widespread use in life sciences applications based on fluorescence excitation and detection. Examples include flow cytometry, drug discovery, and confocal microscopy. The OBIS 514 LS provides a compact and smart alternative to ion lasers at this important legacy wavelength. The OBIS 552 LS offers a new wavelength that provides a single laser alternative to the use of 532 nm and 561 nm lasers. For example: it effectively excites PE while avoiding spill over into both the fluorescein and PE emission bandwidth. It is applicable for most of the dyes typically excited by 561 nm including DsRed, and red fluorescent proteins such as dTomato. Moreover, the absorption coefficient of APC and its tandem dyes is low at 552 nm which significantly simplifies the need for crossbeam compensation.
