Specifications
Configuration	Two symmetrical Czerny Turner monochromators arranged for additive dispersion (or subtractive dispersion - factory set only)
Focal length	Total focal length = 300mm, individual units = 150mm
Slits	Interchangeable fixed slits, micrometer adjusted, variable or motorised
Order sorting	Unit can be fully order sorted from 200nm to 30μm by using option 252 and Bentham OS series of order sorting filters
Grating	33mm square plain gratings kinematically mounted to allow change-over without loss of calibration. A range of gratings covers 200 nm to 30 μm
Aperture ratio	F/4
Resolution	Limit resolution with 1200 grooves/mm grating is better than 0.5 nm
Stray Light	For measurement of notch filter in visible with quartz halogen light, stray light is less than 10^-8
Wavelength scanning	By integral stepping motor and microstepping drive electronics
Maximum scanning speed	For 1200 g/mm grating maximum scanning speed is 30 nm/second
Wavelength accuracy	±0.3nm over normal operating range of 1200 g/mm grating (no software correction) ± 0.05nm with software correction
Reciprocal dispersion	2.7nm/mm with 1200 g/mm grating
PC interface	Integral IEEE-488
Power supply	Mains input 110/220V 50/60Hz
Construction	Single aluminium casting with rebated lid
