Hybrid Auto-Focus

There are two common types of auto-focus systems for microscopes: slit projection and contrast detection.

Slit projection system projects a slit image and then detects the shift in the reflected light. This system is useful when a large focal range is necessary.

Contrast detection system projects a slit pattern and then detects the contrast of the reflected light. This system is useful when focus accuracy is needed. This is possible because this auto-focus system is less affected by sample surface variation.

Design

The controller features the same hardware design as the LV-ECON and has a compact footprint that allows them to be stacked on each other and used anywhere.

Compatibility with LV Series Microscopes

The LV-DAF can be combined with other LV series products. When combined with the LV-ECON, it enables observation under the optimal conditions for each particular sample.

Software Development Kit

Nikon provides a software development kit (SDK) for integrating the LV-DAF into a variety of systems. (Compatibility is only guaranteed for Nikon products.)

Control

The LV-DAF can be controlled from a PC or a DS-L2 digital camera system for microscopes via USB or RS232C.

Auto-Adjustment Program

The Auto-Adjustment Program, included as standard, enables simple and speedy system setup. The program performs immediate auto-adjustment after the user focuses the system and presses the button to start the setup. It is also possible to automatically set/register optimal parameters for each type of sample and recall them in accordance to the sample being photographed.

LED Light Source

The LV-DAF uses a bright LED for the auto-focus light source. And since it also automatically adjusts the auto-focus light volume for the sample, it can support samples ranging from low to high reflectivity.

Multiple Observation Methods

A wide range of observation methods is supported, including brightfield, darkfield, and DIC. Reflective samples and transparent samples are also supported.

Large Focal Range

Focal range is remarkably larger than with contrast detection alone. This means that samples with distortions on their surface, such as a liquid crystal substrate, can be rapidly tracked, thereby enabling speedy focusing.
