Quarter Wave Plate
This compensator gives retardation of ¼ wavelength between the vibration directions.
When the specimen is rotated, with the quarter wave plate inserted between crossed polars
the fast and slow directions of the specimen can be found by the rise and fall of the order of
colour. A maximum rise of colour will occur when the fast direction of the quarter wave
plate coincides with the fast direction of the specimen.
15. Using a Camera
The PriorLab / PriorLux microscopes, when fitted with a trinocular head, can be used with a
range of cameras for documentation purposes. Video cameras, both analogue and digital
provide 'moving' pictures for more advanced imaging applications, while digital 'still' cameras
can be used for basic image capture.
Detailed instructions for the operation of the selected video or digital camera are supplied
with the camera.
Assembly Video Cameras
A.
Screw the c-mount adapter (part no. WXCM1 1.0x or WXCM050 0.5x) to the
video camera
B.
Loosen the knurled silver screw on the c-mount adapter and insert the adapter
with the attached camera into the top of the photo tube on the trinocular head
C.
Tighten the screw to secure the assembly
D.
Connect camera to a PC, framegrabber or analogue monitor as required
E.
To view the image via the camera, pull out the light path selector on the side of
the trinocular head. This diverts 80% of the light to the camera and 20% to the
eyepieces
Assembly Digital Cameras
This is similar to the assembly of video cameras above, but a digital coupler (part no.
MZO1403 suitable for the Nikon Coolpix 4500 or the MZO5503 suitable for the Nikon
Coolpix 5400) and a step down ring (part no. W3000) may also be required depending on
the camera model used.
For more detailed set up information refer to the literature supplied with the camera.
