The LM Series uses a multi‑pin electrical interface that provides: - DC power input (3.1–12 VDC) - RS‑232 for remote communication - TTL modulation input (0–5 V) This pinout is compatible with standard RS‑232 cables or USB‑to‑RS‑232 adapters for easy system integration. Yes. The LM Series supports external TTL modulation from 0 to 5 V, with modulation speeds up to 3 kHz, enabling simple on/off control or low‑frequency modulation for automated analytical instrumentation measurements. Yes. OEM customers commonly integrate the LM Series using: - PC‑based control via RS‑232 - Embedded controllers using RS‑232 or USB‑to‑serial adapters This allows full remote adjustment of laser operating current and temperature setpoints within the stabilized operating range. The LM Series is available in multiple configurations to match OEM optical designs: - Free‑space output - Single‑mode or polarization‑maintaining (PM) fiber‑coupled output. FC/APC connectors - Optional optical isolators for feedback‑sensitive applications. An optical isolator is strongly recommended for any application where optical feedback is possible. Optical feedback can destabilize wavelength‑stabilized diodes or cause latent damage; isolator‑equipped LM models are available to mitigate this risk. The LM Series is designed to be mounted to a heat sink. Integrated temperature control stabilizes the laser diode, but OEM systems must provide: - Proper heat‑sinking - Reasonable airflow or conduction cooling - Minimal airflow near the optical aperture for best wavelength stability Improper thermal management can lead to degraded performance or permanent damage. - OEM versions are supplied without a keyswitch, intended for integration into certified systems. - Non‑OEM versions (e.g., for lab use or U.S. customers) include a keyswitch for laser enable. This allows OEMs to meet system‑level regulatory requirements without redundant safety components. The LM Series achieves stable operation within a few minutes of power‑up, making it suitable for systems requiring fast startup and minimal warm‑up time. Yes. Thanks to SureLock™ technology and PowerLocker® VHG stabilization, the LM Series maintains consistent wavelength and spectral performance from 0% to 100% output power, which is critical for calibrated analytical instruments. Yes. The LM Series is designed for continuous OEM operation when properly heat‑sunk and operated within specified electrical and environmental limits. Power stability is typically ~3% over 5 hours, with excellent short‑term stability. Typical OEM integrations include: - Raman spectroscopy - Interferometry - Metrology and HeNe replacement - Bio‑instrumentation - Particle characterization - Sensing and analytical instrumentation The combination of compact size, integrated electronics, and wavelength stability makes it well‑suited for embedded optical systems.

ORCA is a THz-Raman™ crystallinity meter that uses a scanning laser beam to detect and identify low concentrations of specific polymorphs of Active Pharmaceutical Ingredients (APIs) within complex mixtures. By probing low-frequency lattice vibrations that are highly sensitive to crystal structure, ORCA enables reliable detection of targeted polymorphic forms even at very low concentrations. This rapid, non-destructive technique requires little to no sample preparation and provides a powerful complement to PXRD for solid-form characterization. ORCA supports polymorph screening, crystallinity analysis, and pharmaceutical quality control, enabling fast identification of crystalline phases directly within heterogeneous samples.

WALDO builds on the WPS high-throughput THz-Raman™ screening platform by adding flexible measurement geometries for a wider range of microplate formats. WALDO supports laser scanning through transparent well plates as well as top-down excitation for opaque plates, including stainless steel and Kapton plates commonly used for PXRD experiments. This dual-mode capability allows researchers to perform rapid polymorph screening and crystallinity analysis across different sample holders while leveraging the sensitivity of low-frequency THz-Raman™ spectroscopy to probe crystal lattice structure and molecular composition.

SureLock™ wavelength-stabilized laser diodes and modules incorporate our ultra-narrowband VBGs, forming an external cavity using TruSet to precisely lock the laser’s wavelength to the needs of the application. This enhances spectral brightness and optical performance stability across the entire power range and extended temperature conditions. The extremely short external cavity offers superior mode selection and a smaller footprint than Littrow or Littman cavity designs while reducing the spectral bandwidth of a typical laser by an order of magnitude. With fast warm-up times, flexible power options, and consistent performance, these lasers are ideal for demanding applications such as analytical instruments. Available as modules or components, SureLock® lasers offer flexibility for seamless development and system integration. Applications - Raman spectroscopy - Holography - HeNe replacement - Particle characterization - Analytical instrumentation - Speckle interferometry - Metrology and inspection
