Attaching to an F-Mount Adapter
F-mount adapters use the Nikon bayonet format. To mount the lens on the camera:
1. Locate the large indicator dot on the side of the lens.
2. Note the corresponding dot on the front side of the adapter.
3. Line up the dots and slide the lens into the adapter.
4. Turn the lens counterclockwise until a click is heard. The lens is now locked in place.
In addition to the focusing ring of the lens, there is provision for focusing the adapter
itself. That adjustment is secured by setscrews on the side of the adapter's adjustment
ring. Directions for focusing the adapter and the lens are provided on pages 110 and 111.
Mounting the Adjustable C- to Spectroscopy-Mount Kinetics
Adapter
The adjustable spectroscopy-mount kinetics adapter allows you to move the camera
vertically at the exit plane of an Acton Series spectrograph in order to align the kinetics
rows at the middle of the focal plane for the best spectral quality. The adapter is mounted
to the front of a PIXIS camera and is secured to the camera by a threaded insert screwed
into the camera’s C-mount opening. Refer to Figure 10 when mounting the adapter to the
camera.
Tools Required:
0.050” Hex key
3/32” hex key
Flat screwdriver
Spanner wrench (1.17”/29.7 mm between 0.094”/2.38 mm diameter holes)
Equipment:
Acton Series Spectrograph with light source at entrance port
Kinetics Adapter
SP-2150 and SP-2750 Spectrographs: Use the Model 7050-0107 adapter
SP-2350 and SP-2550 Spectrographs: Use the Model 7050-0104 adapter
Camera with C-mount nose
Procedure:
1. If a light baffle is mounted to the front of the adapter, remove the two 2-56
screws securing it and set the baffle aside.
2. Orient the adapter with the setscrew at the top (see Figure 10) and, using a
spanner wrench or equivalent (distance between holes is 1.17” [29.7 mm]),
tighten the threaded insert into the C-mount opening on the camera.
3. If you are using a light baffle, mount the light baffle to the front of the adapter.
4. Rotate the sliding tube as you gently insert it into the spectrograph’s exit port.
5. With the spectrograph, camera, and light source powered on and connected to the
computer (as required), start the application software. Refer to the appropriate
“First Light” instructions in this manual when focusing and rotationally aligning
the camera to the spectrograph optics.
