Microscope Cameras
-
In contrast to digital cameras for normal photography, microscope cameras are built to meet the demands of high-end science- and research applications. For maximum light sensitivity they use large CCD or CMOS sensors for image acquisition. Color reproduction is often critical, why features like Microscanning or Color-Co-Site Sampling ensure optimal image quality. Due to the lack of a light absorbing color filter monochrome microscope cameras for fluorescence imaging are even more sensitive.

Analog Power Supply
Type NPS-2412
-
National RF's Type NPS-2412 analog power supply was designed to be used in communication equipment where radiated switching inverter noise from conventional “switching type” supplies is not acceptable. The power supply consists of a standard rectified transformer output driving a pair of voltage regulators and filtering networks. The 2412 offers an adjustable voltage output between 2 and 24 volts as well as a fixed voltage output of 12 volts. A maximum of 20 Watts of DC power can be supplied from the unit. As the voltage regulators dissipate power in the regulation process, the power to the load is derated accordingly, dependent on the set voltage to the load. The adjustable regulator is a standard LM-317T integrated circuit device. The fixed regulator is a standard LM 7812 device. Upon customer request, the LM 7812 device may be changed to any voltage rating within the the LM-78xx series of regulators. Contact National RF for this modification if desired.
