    The Skylark 320 NX is designed to replace HeCd lasers in applications such as:

    Laser interference lithography

    Materials analysis

    Flow cytometry

    Raman + photoluminescence

    Semiconductor inspection

    Grating manufacturing

    Why replace your HeCd gas laser with a DPSS alternative?

    Benefit from double the usable power, a stable and reliable output, and a high quality beam without mode cleaning.

    Double your power

    100 mW

    Get twice the output power of a typical 325 nm HeCd system, with 100 mW of efficient UV light that ensures ample power margin for complex setups.

    Leverage long term stability

    ≤ 5 μrad/°C

    HeCd lasers are prone to power drift and thermal instability, which can affect repeatability and accuracy in precision applications.

    The Skylark 320 NX offers wavelength stability of ± 0.2 pm, power stability within ± 2% over 10s of hours, and beam pointing stability ≤ 5 μrad/°C — to maintain consistent illumination and spectral performance over extended operation.

    Benefit from a long maintenance-free lifecycle

    3,000 hours

    DPSS lasers often have a longer lifetime and double the maintenance interval of gas lasers, significantly reducing downtime and operational disruption. With low maintenance requirements, substantially lower operating costs, long lifetime, superior efficiency, and compact footprint — DPSS lasers are a modern and reliable, ultra-stable alternative to legacy gas systems.

    Simplify your setup

    M² ≤ 1.2

    Delivers a clean TEM₀₀ mode with ellipticity > 95%, without extra filtering, providing uniform spatial quality and low noise operation.
