Model 60100 PhotoMax Housing.
PhotoMax is an efficient and versatile Monochromator Illuminator. It uses an ellipsoidal reflector, which surrounds the lamp and collects most of the lamps emission. The output is a very high intensity, full spectrum, focused spot matched to our 1/8 m or 1/4 m monochromators.Versatility distinguishes PhotoMax from the Apex Arc Lamp Sources. Lamps and reflectors are easily interchangeable. With PhotoMax, you can switch between arc and quartz tungsten halogen lamps, and IR elements. Apex Monochromator Illuminators are fixed source illuminators; you cannot interchange between lamp types.
The 60100 PhotoMax lamp housing is attractive to researchers because of its versatility. To provide this versatility, we made PhotoMax a modular lamp housing. We offer a choice of components; selection is based on the application. Table 1 lists the sources, with necessary mounting accessories, that can be operated in PhotoMax. An interface kit and a socket adapter are required; you can interchange lamps, within each lamp family, by simply changing socket adapters. To switch between lamp families, youll need a different interface kit.
Two ellipses are offered for PhotoMax, to match the input cone of Oriel® 1/8 and 1/4 m Monochromators. The ellipses are water-cooled. An aluminum cylinder, attached to the ellipse, holds the water and comes with two fittings to connect to a water recirculator or tap, with standard 0.125-inch (3.2 mm) ID tubing. Water-cooling ensures long life, even with the highest power lamps, and prevents thermal distortion of the reflector.
We offer two reflector coatings: the durable rhodium coating has good visible and excellent infrared reflectivity. Reflectors coated with aluminum with a protective magnesium fluoride (MgF2) overcoat give better performance in the UV and VIS.
PhotoMax uses water cooling to remove heat from the ellipse and from arc lamps (QTH lamps and the 6575 IR Element do not require water-cooling). The ellipsoidal reflectors and arc lamp interface kit include a reservoir for the water, the proper hose fittings and a pressure reducer. A thermal sensing interlock turns off any connected Oriel Power Supply in the event of overheating due to blockage of water flow.If you have access to clean tap water, you may use it. A flow of 0.25 liters (0.5 pint) of water (at <18°C (65°F) per minute at 30 PSI is adequate. We recommend you use Liquid Filters for Light Sources to prevent build-up of organic or mineral contaminants. Input water connections are for 0.125-inch (3.2 mm) ID tubing. If you do not have access to clean tap water, you will need to use a Recirculating Cooler.
The interface kits include the necessary cables to connect to the appropriate power source. The power source must be ordered separately.
The combination of 60130 Beam Turning Assembly (with reflector) and 60143 Table Mounting Kit lets you mount PhotoMax vertically, to an inch or metric optical table, while keeping the output horizontal.The 60130 Assembly houses a full reflector or dichroic mirror that turns the beam 90° (order the dichroic or reflector separately). You can easily interchange optics for different spectral bands.
The Oriel Lamp Housing is designed to operate in a typical laboratory environment (typically 68 to 76 degrees F, up to 45% relative humidity). Temperature and humidity outside of typical laboratory range can contribute to cooling and ignition faults. Cooling issues will cause the over temperature sensor to open, and ignition problems will result from high humidity. Contact a Newport Technical Representative for more information if operating outside the suggested range.
