Click photo to enlarge view of standard window block with countersunk screw holes.  This particular photo shows a VPF-800, reference 16480, that was installed in the sample compartment of a spectrometer.  The sample compartment is rather small and standard pan-head screws on the window block would not have allowed the system to fit in the small space, thus countersunk screw holes were used to allow for flat head screws.

Standard Window Block with Countersunk Screw Holes Option
Janis Research usually uses pan-head screws on the retainers of window blocks, which add about 0.125” to each side of the window block. In cases were space is an issue, talk to your sales engineer about countersunk screw holes in the retainers so that flathead screws can be used, as shown in this photo. This option can be offered on most window blocks with o-ring sealed windows. The window block shown can be used on our model VPF-100, VPF-800, ST-100, CCS-150, CCS-100/202, CCS-100/204 and SHI-4-2.

Modified Window Block
The photos show a standard optical cryostat with a specially modified window block. Two of the windows are our standard 1.63" diameter clear view fused Quartz. The other two windows are a special 2.63" diameter clear view fused Quartz. This window block can be used as an option on many other systems such as ST-100, VPF-100, SHI-4-2, SHI-4-5, SHI-4, CCS-150, CCS-450, CCS-100/202 and CCS-100/204. (The CCS-100/204 an use an optional large window using a different window block.) Contact sales@janis.com for more information.

Click image to enlarge view of PTSHI-4-5 with optional rotating stand.  Reference 17296

Optional Rotating Stand for 4 K and 10 K Cryocooler Systems
This model PTSHI-4-5 features an optional rotating stand that allows the user to flip the entire cryostat upside-down. This is convenient for changing samples. The cryostat itself is rather heavy and it doesn't have any flat surface that will allow it to rest upside-down by itself. Without this rotating stand, gaining access to the sample area would be very difficult and inconvenient. This particular stand is designed to hold the cryostat 50mm above the surface of an optical table but could be designed to hold the cryostat at any height specified by the customer. This stand can be used for 4 K and 10 K Cryocooler systems. Contact sales@janis.com for more information.
