Motorized Filter Wheels

Product catalog summary

Technical Reference Overview: This document provides detailed information on Oriel Motorized Filter Wheels, which are used in conjunction with Oriel Light Sources and Monochromators. These systems are designed to hold up to six 1.0 inch (25.4 mm) diameter filters or apertures, with a clear aperture of 0.87 inch (22 mm).

Key Features:

Filter wheels can be used as low-cost monochromators, variable attenuators, or to hold order sorting filters.
Quick and easy filter insertion is facilitated by a unique design allowing filters to snap in and out of place.
Each wheel includes six filter holders, with additional holders available separately.

Optional Accessories:

The 74012 Rod Mount holds a single 74011 Filter Holder and includes a 1 inch (25.4 mm) long optical rod.

Controller Models:

74040 Low Cost TTL Filter Wheel System: Utilizes a TTL controller with a BNC connector for signal access and a manual forward button.
74041 RS-232 and IEEE-488 Filter Wheel System: Offers RS-232 and IEEE-488 (GPIB) interfaces for computer integration and manual control.

Specifications:

Filter Size: Circular or Square 1 in. (25.4 mm)
Minimum Thickness: 2.5 mm
Maximum Thickness: 10.2 mm
Filter Changeover Time: Less than 2 seconds for adjacent positions

The clear aperture is 0.87 inch (22 mm). They have the Oriel 1.5 inch series flange for direct coupling to Oriel Light Sources and Monochromators. Use a filter wheel as a low cost monochromator, with narrow or broad bandpass filters; as a variable attenuator with neutral density filters; or to hold order sorting filters for your Oriel Monochromator. Quick and Easy Filter Insertion The filter wheel has a unique design. Each of the six positions holds a filter holder that snaps in and out of place, and is accessed from the top of the wheel. This means that you can mount all your 1 inch filters in the holders, and have them ready for quick insertion into the wheel. We include six filter holders with each wheel; others are available separately, under model 74011. Optional Rod Mount The 74012 Rod Mount holds a single 74011 Filter Holder, for use anywhere in your lab. A 1 inch (25.4 mm) long optical rod is included with the 74012 (the 74012 includes a 74011 Filter Holder). Two Models of Controllers We offer two filter wheel systems: • 74040 Low Cost TTL Filter Wheel System • 74041 RS-232 and IEEE-488 (GPIB) Filter Wheel System Low Cost TTL Filter Wheel System The 74040 uses a simple TTL controller to drive and command the filter wheel. A TTL signal moves the filter wheel to the next position. The TTL signal is accessed via a BNC connector on the control box. The controller has a manual “forward” button that moves the filter wheel to the next position. A display shows the current filter position. RS-232 and IEEE-488 Filter Wheel System Choose the 74041 if you are integrating the filter wheel into an optical system using other instruments or if you simply want PC control of your filter wheel. The 74041’s controller has RS-232 and IEEE-488 (GPIB) computer interfaces and a manual “forward” button that moves the filter wheel to the next position.
