  • Practical Optical Interferometry: Imaging at Visible and Infrared Wavelengths (Cambridge Observing Handbooks for Research Astronomers)

    Optical interferometry is a powerful technique to make images on angular scales hundreds of times smaller than is possible with the largest telescopes. This concise guide provides an introduction to the technique for graduate students and researchers who want to make interferometric observations and acts as a reference for technologists building new instruments. Starting from the principles of interference, the author covers the core concepts of interferometry, showing how the effects of the Earth's atmosphere can be overcome using closure phase, and the complete process of making an observation, from planning to image reconstruction. This rigorous approach emphasizes the use of rules-of-thumb for important parameters such as the signal-to-noise ratios, requirements for sampling the Fourier plane and predicting image quality. The handbook is supported by web resources, including the Python source code used to make many of the graphs, as well as an interferometry simulation framework, available at www.cambridge.org/9781107042179.

  • 25pcs Hermetic Pacakge LXD657A-V Photoresistor ,Waterproof of light dependent resistor,Rejects Infrared Wavelength,High Temperature Resistance

    CdS photoconductive cells utilize photoconductive effects in semiconductors that decrease their resistance when illuminated by light. These sensors are non-polar resistive elements with spectral response characteristics close to the human eye (luminous efficiency), thus making their operating circuits simple and small. PART NO.LXD657A-V Allowable Power Dissipation ( PD ) .......... 50 mW ( Derate above 25 ℃:1.0 mW/℃ ) Maximum Applied Voltage (at 25℃) .......... 100V DC or AC VDC Ambient Temperature Range ( TA ) .......... -40 ~+75 ℃ Soldering Temperature*(0.118 inch from base for 3seconds with heat sink).......... 260℃ Light Resistance at 1ftc .......... 20-30KΩ Dark Resistance at 0 Lux*2..........2.0/MΩ Peak Spectral Response..........540Nm ※Light Resistance: Measured at 1ftc with standard light A (2856K color temperature) and 2hr pre-illumination at 40-60ftc prior testing. ※2Dark Resistance:Measured 8 seconds after closed 0ftc.

  • Sightmark IR-805 Compact Infrared Illuminator Flashlight

    Combined with any night vision riflescope or monocular, the Sightmark Infrared Illuminator acts as a flashlight during night vision use. With the Infrared Illuminator, the user can illuminate the target without the prey detecting it. The Sightmark IR Illuminator is great for indoor and outdoor use, where there is low ambient light, such as during a SWAT raid in a dark warehouse or varmint hunting out on a moonless night. Operable with two AAA batteries, the Sightmark Infrared Illuminator offers two power options, a low output at 70mw and a high output at 100mw for a more powerful and brighter experience. Featuring a battery life of 20 hours, the Infrared Illuminator also has an adjustable beam focus to widen or narrow the stream of light. The adjustable beam focus is perfect for not only user preference, but for adapting to long and short ranges and indoor/outdoor use. For closer ranges or indoor use, where target acquisition is important, the wider beam will cover a wider field of view. The design of the IR flashlight is great for handheld use and the location of the on/off switch makes it easy to operate with the thumb. As long as the enemy does not have night vision, the IR flashlight can be used for covert signaling at night. The Infrared Illuminator comes with a standard one...
