A method of laser processing a workpiece includes: focusing a pulsed laser beam into a laser beam focal line directed into the workpiece such that the laser beam focal line generates an induced absorption and produces a defect line along the laser beam focal line within the workpiece. The laser beam focal line has length L and a substantially uniform intensity profile such that the peak intensity distribution over at least 85% of the length L of the focal line does not vary by more 40%, and in some embodiments by no more than 30 or 20% from its mean peak intensity.

A multi field of view hyperspectral imaging device and method for using the same which can be used in many applications including short wavelength infrared (SWIR) and long-wavelength infrared (LWIR) applications are presented herein. In one embodiment, the multi field of view hyperspectral imaging device comprises multiple fore optics, multiple fold mirrors, a slit including a multiple openings, a spectrometer, and a 2-dimensional detector.

Multi field of view hyperspectral imaging device and method for using same

An optical apparatus has a primary optical element having a primary spherical optical surface with a primary center of curvature, wherein the primary spherical optical surface has a peripheral portion that extends outside a usable aperture of the optical apparatus, and a secondary optical element. A mount suspends the secondary optical element spaced apart from the primary optical element, wherein the mount comprises a number of leg sections, each leg section extending between the primary and secondary optical elements. Each leg section terminates in a spherical mating surface that rests against the peripheral portion of the primary optical element. The spherical mating surface has a mating surface center of curvature that is substantially concentric with the primary center of curvature.

Precision optical mount

A optical instrument (e.g., coronagraph) is described herein that has a pick-off mirror with a surface having an array of reflective structures (reflective occulting mask) machined therein which enables an optical image of one or more low intensity objects (e.g., planets) to be obtained when the low intensity object(s) are located in close proximity to a high intensity object (e.g., sun). Also described herein, is a method for manufacturing the pick-off mirror which has a surface with an array of reflective structures (reflective occulting mask) that are machined therein.

Microlens arrays, especially useful for optical coupling in optical switches of fiber optic telecommunications systems are produced with optical quality requisite for such applications with a replicating tool. This tool is made using a form tool set up in a rotating spindle of a precision air bearing milling machine at an angle of inclination such that the point of zero surface velocity is maintained outside of the surface of substrate machined to make the tool for replicating the arrays. The tip of the form tool has a profile corresponding to the profile of the lenses of the array, such as a generally circular profile having a radius centered at the axis of rotation of the form tool. The form tool is reciprocated with respect to the surface so as to form cavities of the desired profile, radius and depth which corresponds each identical lens of the array. To provide arrays the form tool is raised and the substrate is translated to preprogrammed positions. When these positions are reached the reciprocation and cutting action of the tool is repeated. The replicating tool containing cavities defining the lenses of the array which provides a master. The master may be used to replicate identical arrays. Lenses so formed may be positive with convex surfaces. Arrays of lenses, which are negative and have concave surfaces, may be made using an intermediate master replicated from first master. The profile of the lenses may be altered by changing the shape of the form tool cutting surface or by translating the substrate during reciprocation of the formed tool as the profile of each cavity is being machined. In addition to lenses having optical power, reflectors with desired power may also be made with the machined master or intermediate master.
