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 30¥ìm 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
¡¾0.2nm of the true throughput range
Dispersion
1.8nm/mm with 1800 grooves/mm grating
PC interface
Integral IEEE-488
