Schematic view of a rigid borescope Borescope in use, showing typical view through the device. A borescope (occasionally called a boroscope, though this spelling is nonstandard) is an optical instrument designed to assist visual inspection of narrow, difficult-to-reach cavities, consisting of a rigid or flexible tube with an eyepiece or display on one end, an objective lens or camera on the ...
When using a micrometer to set a dial bore gauge, the accuracy of the measurement will be 0.002 inches or 0.0508 millimeters. A ring gauge can be used to obtain higher accuracy at a higher cost and higher time requirement. When a dial bore gauge is set using a ring gauge, overall accuracy can be within 0.0001 inches or 0.00254 millimeter. [2] A ...
35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...
Dial indicators typically measure ranges from 0.25 mm to 300 mm (0.015in to 12.0in), with graduations of 0.001 mm to 0.01 mm or 0.00005in to 0.001in (imperial/customary). Various names are used for indicators of different types and purposes, including dial gauge , clock , probe indicator , pointer , test indicator , dial test indicator , drop ...
The T-mount is a standard lens mount for cameras and other optical assemblies. The usual T-mount is a screw mount using a male 42×0.75 (42 mm diameter, 0.75 mm thread pitch) metric thread on the lens with a flange focal distance of 55 mm and a mating female 42mm thread on a camera adapter or other optical component.
Turkey. The main feature of many Thanksgiving dinners is the turkey. You'll be happy to know that it can be given to your dog. You'll want to be careful how you serve it though.
It is more accurately known as the M42 × 1 mm standard, which means that it is a metric screw thread of 42 mm diameter and 1 mm thread pitch. (The M42 lens mount should not be confused with the T-mount , which shares the 42 mm throat diameter, but differs by having a 0.75 mm thread pitch.)
With one fateful fall, Chet Holmgren's promising young season was flipped on its head. The Oklahoma City Thunder big man suffered a right iliac wing fracture on Sunday night in a 127-116 loss to ...
