Background

Allen Krisiloff founded Triptar in 1993 in order to build a company devoted to the design and development of optical systems incorporating fine mechanics, electronics, and software control. It is still a small company, but it has managed and delivered several large and sophisticated development projects. Mr. Krisiloff’s Optical Engineering experience began at the University of Rochester's Laboratory for Laser Energetics (LLE) while an undergraduate in Physics during the late 1970's. He designed, built and tested picosecond laser oscillators and test instrumentation. After the LLE, he designed optics and opto-mechanics for machine vision modules in one of Eastman Kodak's manufacturing units. He was recruited to Hampshire Instruments in 1984 to help build the Nd:YLF oscillator and preamplifiers for the early demonstration of a laser triggered X-ray source. Then he moved to a position where he designed objective lenses and scanning lenses for medium and high production applications. In 1991, he moved to GCA to manage a multidisciplinary team of engineers. His group was responsible for all metrology in the process of manufacturing a deep UV step-and-repeat camera lens for the semiconductor industry. In 1993, Mr. Krisiloff started Triptar as an independent consultant. He took on design and analysis jobs. Soon, he started to rent laboratory space from a friend to build and test prototypes. In 1995, Triptar joined efforts with Amarel Precision Instruments to design and build a remote controlled double microscope system, called DFOS (Dual Field Optical System), to serve as a non-contact probe on a coordinate measuring machine. Mr. Krisiloff formed and directed a team of 13 employees and subcontractors to create the DFOS instrument. It featured complete control from a PC running Windows, specialized optical and electronic designs, variable magnification, an autocollimator, machine vision metrology based upon proprietary image analysis algorithms, and a database to store and manipulate measurements. After this project, Amarel hired Triptar to commercialize SurfaceScope™, a confocal microscope technology invented at Oxford University. A Confocal microscope presents to the observer only portions of the specimen which are currently in-focus by eliminating the out-of-focus parts of its image. Contrast can be improved and points in the specimen can be unequivocally associated with their positions in 3-space. Using rendering algorithms, the specimen is mathematically modeled in 3D. The SurfaceScope™ microscope projects a one dimensional spatial frequency onto the specimen in such a way that only the in-focus portions of the specimen are tagged with the frequency. A specially designed electro-mechanical stage carries a Ronchi ruling and is placed into the field stop of the microscope. A PC controls the spatial phase of the ruling as it is projected, and the PC synchronizes image capture and analysis with the ruling’s position. Triptar now serves as the North American distributor for SurfaceScope™. Triptar also designs and manufactures lenses on contract for subassemblies in medical and industrial devices.
