Fewer total images required for large high-resolution image stitching

The large 25 mm FOV of the A1 HD25/A1R HD25 reduces both the required number of images for stitching large images and image acquisition times, enabling efficient, high-throughput imaging of even large-scale samples. The number of required images can be greatly reduced, in particular for large 3D (XYZ) image stitching.

Increase analytical throughput without compromising image resolution

The combination of a high-speed resonant scanner and large field of view forms an ideal platform for high-resolution screening assays. It dramatically reduces the time needed to analyze multiple samples and conditions.

A1R HD25 high-speed, high-definition resonant scanner

• A1R HD25

High definition imaging up to 1K x 1K

1024 x 1024 pixels enables acquisition of high-resolution, high-quality images at lower magnifications, enabling compatibility with a wide range of samples.

Low phototoxicity for live cells

High speed imaging capability up to 720 fps, in combination with a large field of view, dramatically increases imaging throughput. This scanning method reduces the exposure time of the sample to excitation light, minimizing phototoxicity and photobleaching.

Superior images for both macro and micro imaging

Capture large-scale overview images as well as high magnification images with the same instrument. The 25mm FOV of the A1 HD25/A1R HD25 is effective for observation of large samples, while its 1Kx1K high-definition is ideal for the observation of minute structures.

Highly sensitive detector options for various types of fluorescence labels

A1-DUG-2 GaAsP Multi Detector Unit

The A1-DUG-2 is a 4-channel detector unit equipped with high-sensitivity GaAsP PMTs, allowing acquisition of bright signals with minimal background noise, even when fluorescence is weak or the detector unit is used with a high-speed resonant scanner.

A1-DUVB-2 GaAsP Detector Unit

A1-DUVB-2 is equipped with a high-sensitivity GaAsP PMT and allows spectral imaging using both galvano and resonant scanners. This is a fully tunable emission detector unit capable of spectral imaging with user-defined emission bandwidths as low as 10 nm. Variable bandpass mode and continuous bandpass mode are selectable based on the applications and the images can be spectrally unmixed. The option to add a second fixed bandwidth emission channel enables simultaneous multi-channel imaging.

A1-DUS Spectral Detector Unit

The A1-DUS can acquire spectral images at a high wavelength resolution of at least 2.5 nm. 32 channels of fluorescence spectra (up to a 320 nm wavelength range) can be acquired with a single scan, enabling fast imaging at up to 24 fps (512 x 32 pixels). Simultaneous excitation with up to four lasers enables spectral imaging across wider bands.

It precisely unmixes closely overlapping spectra of fluorescent labels and eliminates autofluorescence. Real-time unmixing during image acquisition is highly effective for FRET analysis.

The unique V-filtering function, with its capacity for filter-less intensity adjustment, allows arbitrary spectral ranges to be selected from 32 channels and combined to perform the filtering function of up to four filters, enabling imaging with the optimal intensity of each fluorescence probe.

Superior optical technologies to support all confocal applications

Nikon provides a broad range of high-NA objectives with unrivaled optical quality to redefine the boundaries of confocal imaging. Options include silicone oil immersion objectives for thick live cell imaging, large-FOV low-magnification objectives and easy-to-use dry objectives. Chromatic aberrations are corrected from ultraviolet to near infrared range, enabling excellent multicolor imaging.
