Combined high numerical aperture and long working distance

Objective lenses are crucial to a microscope’s performance. The MXPLFLN objectives add depth to the MPLFLN series for epi-illumination imaging by maximizing numerical aperture and working distance at the same time. Higher resolutions at 20X and 50X magnifications typically mean shorter working distances, which forces the sample or objective to be retracted during sample exchange and requires slow sample handling during observation. In many cases, the MXPLFLN series’ 3 mm working distance eliminates this problem, enabling faster inspections with less chance of the objective hitting the sample.

Broad spectral range

From visible to near-infrared (NIR), our advanced optical fabrication and coating technology provides users and manufacturers with a variety of objective lens and tube lens combinations to simplify their system requirements with standard products.

Wide variety of revolving nosepieces

As the demand for automation increases, so does the demand for motorized revolving nosepieces. Evident has proven performance with the U-D5BDREMC and U-D6BDREMC five-and six-position motorized revolving nosepieces. Now the U-D5BDREMC-VA class 1 clean room compatible motorized revolving nosepiece removes dust and other particles using a vacuum. Manual, coded, and centerable revolving nosepiece as well as adapters for a single objective lens can be configured into BXC assemblies.

Autofocus sensing unit

The BXC-FSU is a Class 1 laser product¹ to enable active multispot sensing to monitor the direction of the focal position and focus status. This sensor works well for low-contrast samples like bare wafers. A unique algorithm outputs a stable focus signal regardless of the objective lens magnification and noise caused by peripheral light. The command reference manual, instruction manual, and sample software are available on our website.²

¹ The Class 1 laser is contained, so no additional safety measures are required.
² Application manuals are available on request.

Compact control box

The BXC-CBRML and BXC-CBB control boxes have small footprints, no fan, and variable mounting options (e.g., wall or ceiling). Depending on the control box, functions like the MIX slider, illuminator, motorized revolving nosepiece, and LED light source can be integrated and controlled using your software.
