The APEX2-QTH illumination system is designed as a compact, fully integrated solution for a wide variety of applications. This turnkey solution produces a collimated 1.3-inch (33 mm) diameter output beam. Just install the lamp, connect the power cord and switch on the power – then the system is ready for use.

The lamp operates with a built-in power supply, so no current or power adjustments are required. The lamp is designed with an ellipsoidal reflector, capturing additional light to increase optical power. Lamp replacement is easy – no alignment is needed. The APEX2-QTH includes a manually operated shutter, which may be closed while the lamp is warming up. The output intensity can be adjusted using an external DC power supply (sold separately).

The light source is coupled to a filter wheel, where up to six filters (sold separately) may be installed. A large, easy to read digital display indicates which filter is in the light path. The filters may be selected using several methods, including manual control and software. For those who wish to create their own programs, low-level commands may be sent to the system via its USB connection to the computer.

The output flange of the APEX2 is compatible with the 1.5-inch Oriel flanging system. An adjustable output lens is used for f-number matching, making it compatible with the following instruments:

•Cornerstone 130B Monochromator
•Cornerstone 260B Monochromator
•MS257 Monochromator
