BXC Series
The BXC series offers the high-quality microscope components you know and trust from Evident, but in a compact, mountable, and configurable format. These off-the-shelf optical-mechanical assemblies are ready to be designed into your scientific instruments and devices.
Overview
High-Quality Compact Microscope Assemblies
The BXC series offers high-quality microscope components that suppress variations and provide stable imaging quality. These compact microscope assemblies can be quickly and easily integrated into your system with a variety of options.
High-Performance Objective Lenses
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.
Improved image flatness
The image flatness of the MPLFLN 2.5X, 5X, and 5X brightfield/ darkfield objectives has been improved, making it faster to obtain stitched images at low magnifications. For higher throughput in darkfield observation, we introduced a brightfield/darkfield 2.5X objective—the MPLFLN2.5XBD.
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.

Wavefront aberration control
High-end manufacturing processes—such as wavefront aberration-controlled selection of lens assemblies—are used for MXPLFLN series objectives. This process keeps variation in device performance to a minimum.

What Configuration Will You Build?
Part of our BX™ microscope series, the BXC series has a wide range of options for each part, including the objective lens, revolving nosepieces, and Illuminators. The series is designed to let you to choose freely according to your use case. The versatility and modularity of these components make them a good choice for inspection or imaging applications, such as instruments designed for wafer alignment, bump measurement, and image stitching.

Advanced Options for System Design and Automation
Versatile directional darkfield
Darkfield is used to observe scattered or diffracted light from a sample—such as scratches or flaws—on a mirror surface or semiconductor wafer. The MIX slider realizes darkfield without large, dedicated optics and enhances traditional darkfield with 16 individually controllable LEDs, enabling you to control the direction of light shining on the sample. In addition, this directional darkfield technique, achieved by using the MIX slider, can be combined with brightfield, simple polarized light, or fluorescence observation.

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.
