Features

Two 50 W QTH Lamp Choices

Two different 50 W QTH lamps are offered. The 6332 is a short filament type QTH lamp. Short filament QTH lamps have better shock and vibration due to their compact construction and can be more useful for reimaging the filament onto a small input slit of a monochromator, for example. The 6337 is a long filament type QTH lamp. Long filament QTH lamps have an extended average lifetime.

100 W QTH Lamp Option

The 6333 is a 100 W QTH lamp for users that require a larger filament size and additional light output intensity.

High Stability

The OPS-Q250 power supply provided with these light sources is a highly regulated power supply. Much of an QTH lamp's stability in wavelength and output intensity is due to keeping the temperature and pressure of the gas inside the lamp's envelope as constant possible. The OPS-Q250 power supply provides highly stable voltage and current supply to the lamp's filament, keeping the lamp's ripple to less than 0.05% rms while maximizing the lifetime of the lamp.

Economical, Convective Cooled Lamp Housing

The 60000 Series Q Lamp Housing uses convection cooling to maintain a safe operating temperature for Oriel's low wattage lamps, without the loud noise or induced vibration of the typical cooling fan. This housing is popular for researchers that need an inexpensive, compact, versatile lamp housing. With the right Interface Kit and Socket Adapter, all Oriel Arc Lamps and QTH Lamps up to and including 100 W can be operated in this lamp housing. The characteristics of the output light can be changed by simply swapping the condenser lens.

Ability to Mount QTH Lamps Horizontally or Vertically

QTH lamps can be mounted inside the Series Q housing horizontally or vertically. Mounting a QTH lamp horizontally orients the filament vertically, making this the preferred position for matching the light emitting filament onto the vertical slit of a monochromator or other light analysis device.

Four Different Condenser Lens Options

The four condenser lens options offered with these kits differ in the type of lens used and F/# (F Number). Two specific lens types are used in these condenser lens configurations:

  • Plano Convex: Most economic lens option, utilizes an asymmetric lens shape to minimize spherical aberration
  • Aspheric: The front surface of an aspheric lens gradually changes in curvature from the center of the lens to the edge. This shape reduces spherical aberration more effectively than a Plano Convex Lens

F/# should also be considered when selecting a condenser lens. A smaller F/# means the lens is placed closer to the light source inside the lamp housing. This allows for greater radiant flux as more light is collected by the lens. However, this also causes greater lens aberration. As a result, more light does not mean more quality light. Higher F/#'s are suggested if a high quality collimated beam is needed from the output of the lamp housing. However, lower F/#'s are suggested for coupling to a monochromator due to their higher throughput.

Simultaneous Illumination of Up To Four Samples Possible

The 60000 Series Q Lamp Housing contains four output ports. These output ports can remain plugged if unused, or fitted with a condenser lens assembly. If a different condenser lens assembly is mounted to each output port, four simultaneous light outputs, each of a different wavelength emission and beam characteristics can be achieved using a single lamp.

All Necessary Components for Lamp Operation Included

Each light source includes a QTH lamp, socket adapter, lamp housing interface kit, power supply, rear reflector assembly, lamp housing, and condenser lens assembly. After a quick and easy assembly, the light source is ready for use and easily integrated into a user's setup. The included lamp housing is capable of operating all Oriel QTH lamps 100 W and lower in input power and allows the user to swap condenser lens assemblies for different light output characteristics.
