Overview
No matter how advanced Raman microscopes become in functionality and versatility, the paramount importance in measurement remains obtaining high-quality Raman spectra with high resolution.
The InFocus λ RS eliminates the optical alignment adjustments that have plagued many measurers and makes focusing fully automated. A new concept of laser Raman microscopy that enables anyone to make Raman spectroscopy measurements at the highest resolution at any time.

Guaranteed spatial resolution of 350 nm, close to the diffraction limit.
The high-quality optical system, which efficiently collects light up to the diffraction limit, is fundamental to microscope performance. InFocus λ RS achieves spatial resolution exceeding 350nm when using a 532nm laser and a 100x objective lens with NA 0.90. Thanks to its robust optical system, it maintains high spatial resolution consistently after delivery, eliminating the need for daily alignment adjustments.
Equipped with a spectrograph featuring a balanced focal length of 500mm, ensuring excellent resolution and brightness. It excels in peak position accuracy, making it an optimal choice for stress evaluation.

Dedicated optics for assisting high-resolution measurements
By combining the spectrograph's slit with the region of interest (ROI) of the electrically cooled CCD, it adopts a cross-confocal optical system that achieves performance equivalent to a pinhole. With easier adjustment, narrowing down the confocal aperture size for high-resolution measurements becomes a practical choice.
Standard equipped with Auto Focus Tracking (AFT) function, utilizing a laser for autofocus detection and tracking focus at a rate of 800 updates per second. This feature helps avoid measurement failures due to stage drift during day-night or long-duration mapping measurements, dramatically reducing analysis time.
