Excelsior One

INNOVATIVE DIRECT DIODE AND DPSS LASERS

  • Largest portfolio of up to 14 different wavelength options
  • High brightness direct diode technology
  • One platform offering free space and fiber-coupled models
  • One box with laser head and controller

The Spectra-Physics Excelsior® One™ series is a new line of UV, visible, and near IR CW lasers based on Spectra-Physics It’s in the Box™ design with the laser head and controller combined in a single, compact package. The Excelsior One series is available as free space and fiber-coupled lasers that include fourteen different wavelengths and delivers up to 500 mW of average power. The series includes both direct diode and diode-pumped solid state (DPSS) laser technology in a compact package offering multi-mode and single frequency options using the exact same mechanical footprint.

One Platform for 14 Wavelengths – 375, 405, 445, 473, 488, 515, 532, 542, 553, 561, 594, 642, 785, and 1064 nm

The Excelsior One series offers 1064 nm in the infrared, while the visible wavelengths options at 473, 515, 532, 542, 553, 561, and 594 nm are based on patented frequency doubling techniques for the DPSS models. Direct diode models – with the option of high speed modulation and serial software interface – are available at 375, 405, 445, 488, 642, and 785 nm. For ease-of-use and laser power control, all Excelsior One lasers are equipped with an RS 232 software interface.

The Excelsior One lasers are ideal for customers who rely on modularity in their instrument design. With the Excelsior One series, customers can choose among over 50 different versions in a single footprint and a single supply voltage. This enables maximum independence and the fewest design constraints.

Fiber-Coupled Models

The Excelsior One series is also offered with fiber-coupled options from 405 nm to 1064 nm using single mode, polarization maintaining fibers. These fiber-coupled lasers offer outstanding power stability in harsh operating environments, and a polarization extinction ratio (PER) of less than -30 db over the specified operating temperature range. The fiber-coupled Excelsior One lasers are terminated with a FC/APC connector.

new High Brightness 488 nm Direct Diode

The new Excelsior One NB 488 provides the increased brightness desired for fluorescence-based applications such as flow cytometery, confocal microscopy and multi-array readers. The narrow linewidth of less than 0.5 nm is ideal for coupling light through an acousto-optical tunable filter (AOTF).
