Abstract
Abstract This invention provides an improved mounting or clamping device for optical components such as lenses in which a clamping ring which clamps a component against a shoulder in a mounting body has a deformable resilient lip which bears against the component and which accommodates thermal expansion and contraction in the mounting body, avoiding strain in the optical component. The clamping ring may have a single annular deformable lip or a number of circumferentially regularly spaced apart lips.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
94 words
A mounting device for an optical component, comprising a hollow body having an internal shoulder against which an optical component bears in use of the device, and an annular clamping element in screw-threaded engagement with the body, wherein the improvement consists in the clamping element having at least one radially inwardly projecting integral deformable resilient lip which, upon assembly of an optical component in the device, bears against a surface of the optical component opposite that which bears against the shoulder to clamp said component resiliently against the said internal shoulder of the body.
Claim 2
Dependent Claim
94 words
A mounting device for an optical component, comprising a hollow body having an internal shoulder against which an optical component bears in use of the device, and an annular clamping element in screw-threaded engagement with the body, wherein the improvement consists in the clamping element having at least one radially inwardly projecting integral deformable resilient lip which, upon assembly of an optical component in the device, bears against a surface of the optical component opposite that which bears against the shoulder to clamp said component resiliently against the said internal shoulder of the body.
Claim 3
Dependent Claim
59 words
The mounting device defined in claim 1, wherein the internal shoulder is annular and bears against a circumferentially continuous region of the optical component in use of the device, and wherein the clamping element has a single annular inwardly projecting deformable lip which upon assembly of the device exerts a circumferentially uniformly distributed clamping force on the optical component.
Claim 4
Dependent Claim
49 words
The mounting device defined in claim 1, wherein the clamping element has a number of circumferentially evenly distributed radially inwardly projecting deformable lips arranged around its internal periphery, which lips engage a said optical component at a number of evenly spaced apart positions upon assembly of the mounting device.
Claim 5
Dependent Claim
42 words
The mounting device defined in claim 2, wherein the annular lip of the clamping element has a number of circumferentially evenly distributed axially deformed portions which engage a said optical component at regularly spaced apart circumferential intervals in use of the device.
Claim 6
Dependent Claim
22 words
The mounting device defined in claim 1, wherein the said deformable lip is formed integrally with the remainder of the clamping element.
Claim 7
Dependent Claim
136 words
A mounting device for an optical component, comprising a hollow body having an internal shoulder against which an optical component bears in use of the device, and an annular clamping element in screw-threaded engagement with the body, wherein the improvement consists in the clamping element having at least one radially inwardly projecting integral deformable resilient lip which, upon assembly of an optical component in the device, bears against a surface of the optical component opposite that which bears against the shoulder to clamp said component resiliently against the said internal shoulder of the body, and wherein the said clamping element has a rigid substantially non-deformable part, the deformable lip overlying the said rigid part and being normally spaced from the latter by a gap which is closed when the clamping element is tightened on the body.
Claim 8
Dependent Claim
136 words
A mounting device for an optical component, comprising a hollow body having an internal shoulder against which an optical component bears in use of the device, and an annular clamping element in screw-threaded engagement with the body, wherein the improvement consists in the clamping element having at least one radially inwardly projecting integral deformable resilient lip which, upon assembly of an optical component in the device, bears against a surface of the optical component opposite that which bears against the shoulder to clamp said component resiliently against the said internal shoulder of the body, and wherein the said clamping element has a rigid substantially non-deformable part, the deformable lip overlying the said rigid part and being normally spaced from the latter by a gap which is closed when the clamping element is tightened on the body.
Claim 9
Dependent Claim
145 words
A mounting device for an optical component, comPrising a hollow body having an internal shoulder against which an optical component bears in use of the device, and an annular clamping element in screw-threaded engagement with the body, wherein the improvement consists in the clamping element having at least one radially inwardly projecting integral deformable resilient lip which, upon assembly of an optical component in the device, bears against a surface of the optical component opposite that which bears against the shoulder to clamp said component resiliently against the said internal shoulder of the body, and wherein the internal shoulder is annular and bears against a circumferentially continuous region of the optical component in use of the device, said clamping element having a single annular inwardly projecting deformable lip which upon assembly of the device exerts a circumferentially uniformly distributed clamping force on the optical component.
Claim 10
Dependent Claim
145 words
A mounting device for an optical component, comPrising a hollow body having an internal shoulder against which an optical component bears in use of the device, and an annular clamping element in screw-threaded engagement with the body, wherein the improvement consists in the clamping element having at least one radially inwardly projecting integral deformable resilient lip which, upon assembly of an optical component in the device, bears against a surface of the optical component opposite that which bears against the shoulder to clamp said component resiliently against the said internal shoulder of the body, and wherein the internal shoulder is annular and bears against a circumferentially continuous region of the optical component in use of the device, said clamping element having a single annular inwardly projecting deformable lip which upon assembly of the device exerts a circumferentially uniformly distributed clamping force on the optical component.
