The NASA Kepler mission is currently in its second phase of operation since the recovery of the craft and launch of K2. A couple of years ago Kepler lost some important technology and had to return to Earth, but now with K2 being launched, the campaigns can continue.
The mission still retains its original goal of discovering earth-like planets and determining if any are habitable.
Lenox Laser was responsible for fabricating what the scientists over at NASA call the Starfield Plate. This plate consists of stainless steel laser drilled with an array of holes as small as 3 microns in diameter with the purpose of performing photometry.

Lenox Laser Pioneering New High-Powered Laser Technologies
Blog“The high power laser parameters relevant to selecting an aperture suitable for use in the optical beam delivery system are aperture substrate material, laser power or energy, area and time.”
– Gilbert R. Smith, P. F.
The development of high power lasers includes but is not limited to the following methods: Q-switching, cavity-dumping, and mode locking. In these cases, lasers operate in a pulsed regime when the single pulse or package of pulses is generated at a certain timing rate.
High energy and high power apertures are intended to be used in the optical transfer assembly using a large laser as a source. The parameters such as laser power and pulse energy, pulse duration and repetition rate become important.

Massively Parrallel X-Ray Holography using Pinhole Technology
BlogBERKELEY, CA – The pinhole camera, a technique known since ancient times, has inspired a futuristic technology for lensless, three-dimensional imaging. Working at both the Advanced Light Source (ALS) at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory, and at FLASH, the free-electron laser in Hamburg, Germany, an international group of scientists has produced two of the brightest, sharpest x-ray holograms of microscopic objects ever made, thousands of times more efficiently than previous x-ray-holographic methods.
Small Hole Applications
BlogThe small hole, orifice or aperture is the key element of any device or instrument designed to control or measure the flow rate of a gas or liquid. In the recent past, the gasoline piston engine went through a transition that improved performance and reliability. Precision made small holes brought to life the fuel-injection process, an important technology that has superseded the carburetor. For general applications, precision, fixed control of gas flow rate is made possible through placement of a small hole in the flow passage. Under fixed positive pressure conditions, the small hole becomes the flow rate calibration device. In the area of high vacuum helium leak detector calibration devices, the small holes provides the calibrated leak rate.
Semiconductor Integrated circuits and other semiconductor devices are the foundation of today’s electronics industry. The development and production of semiconductor devices and manufacturing equipment bases heavily on ion or molecular beam processing technology. Ion beam drilling devices require the use of small, precise holes for beam forming.
Optical from early days, optics used small holes to illustrate the wave property of light. An annular diffraction pattern of interference fringes may be observed from the passage of light through a small hole. Small holes provide important functions in optical transfer assemblies. They provide the means for beam alignment, spatial filtering, aperture limiting, image analysis, and image processing.
Electron Beam, a mask containing an array of small holes, is used to control the electron beam emission in the color television picture tube. The electron microscope uses apertures as small as 2 microns in diameter to maximize control of electron beam emissions and profiling.
Pinhole Photography Competition with Goucher

The Messenger is scheduled to leave July 30th, 2004 and should fly by Venus in October 2006 and then finally reach Mercury by January 2008.
NASA Kepler Mission
NewsThis special purpose space mission that has been proposed to NASA Headquarter’s Discovery Program as a practical method for detecting Extrasolar Terrestrial Planets, that is, rocky and Earth-size. Lenox Laser fabricated a custom Starfield Plate for the Kepler Mission.
Quote from NASA’s Kepler Mission Web Site
“The star plate has a large number of holes of various sizes (used to perform time-variant relative photometry) and they are placed in many locations across the field-of-view to support the suite of tests described earlier. The plate is made of 50-micron thick stainless steel and opaque (transparency of less than one part in a million). The hole pattern was drilled with a laser beam by Lenox Laser, with some holes as small as 3 microns diameter (for the mv=19 stars).
There are 84 holes for the 9<14 target stars in the uncrowded region of the plate. These are used to isolate the effects of faint background stars, bright stars, smearing, etc. Some of these have very nearby stars as faint as mv=19 to demonstrate that stars five magnitudes fainter than the target star are not a problem even when spacecraft jitter is simulated. Bias-Smear Graphic of 84 Star plate Array There is a crowded portion of the plate with 1540 stars having the same star field density to mv=19 as the actual Cygnus region to be viewed by the Kepler Mission. This region was used to demonstrate the ability to perform the high-precision relative photometry even in crowded fields."
