Symmetrical Czerny Turner with alternative slit positions
Focal length
300 mm
Aperture ratio
F/4.2
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
69mm2 plane gratings kinematically mounted to allow change-over without loss of calibration.
Resolution
M300HR: 0.15nm, M300E: 0.5nm
Maximum resolution obtainable is limited by misfocus in the collimating system. In the HR version, one of the collimating mirrors is mounted on a translation stage allowing fine positioning. All instruments are set up to achieve the specified resolution before delivery.
Stray Light
(at full aperture with 1nm bandwidth)
1.5 bandwidths from laser line: 0.18%
3.0 bandwidths from laser line: 0.025%
10.0 bandwidths from laser line: 0.004%
Light gathering capability
0.63 = slit height/(f number2 x dispersion) nm/mm
Wavelength scanning
By integral stepping motor and microstepping drive electronics
Wavelength readout
4 digit display reading directly in nm with readability of .02nm
Wavelength step
Each step of the stepping motor results in a wavelength change of 0.01nm for the HR version and 0.05nm for the E version
Maximum scanning speed
For 1800 g/mm grating,
M300HR: 4nm/s, M300E: 20nm/s
Wavelength accuracy
±0.2nm of the true throughput range
Dispersion
1.8nm/mm with 1800 grooves/mm grating
PC interface
Integral IEEE-488
Power supply
Mains input 110/220V 50/60Hz
Construction
Single aluminium casting with rebated lid
