Programmable Filter Wheels features a removable filter carrier system that enables the wheel to be configured for 25 mm diameter, 32 mm diameter filters, or any combination of 25 and 32 mm diameter filters. A proprietary built-in electronic shutter increases reliability and is designed for up to 20 million cycles. It has high resolution encoding is used to provides accurate filter positioning. Adapters are available to mount the new filter wheel to any commonly available microscope. It provides fast, automated and efficient optical filter changing for microscopes. The filter wheel position is digitally encoded which makes it immune to slippage and skipping errors. Accurate filter positioning is essential to eliminate imaging errors that affect the optical performance .The LEP filter wheel is driven by a DC servo motor specifically selected for smooth, quiet, damped wheel motion. It provides flexibility and expandability. The modular controller provides high performance and flexibility. It is widely supported by almost any available imaging software application.
Programmable Humidity Chamber has two sets of controls featuring proportional, integral and derivative parameters. It also has reset windup inhibit and reset clipping facilities. This control system provides control setting and indication resolution of 0.1° and +/- 0.1% relative humidity. This controller has 200 program steps for up to 99 recipes and 16 programmable events. A host computer is used to communicate with the programmer. All recorder functions can be easily configured through the keys on the front panel. The special swing-out mounting bracket allows the recorder/controller to be pivoted from the side of the control compartment to the front if desired. The high efficiency air circulation system is delivering horizontal airflow that is an integral part of chamber construction. This direct drive design has an extended shaft electric motor coupled to a stainless steel centrifugal blower wheel.
