Detailed information
-
<Wideband Wavelength Tunability> It covers a wide wavelength range from 369 to 530 nm and from 630 to 1300 nm, accommodating a broad spectrum of applications from short-wavelength uses to those requiring wideband scanning. The Littrow configuration enables a wide continuous tuning range without mode hopping, making it ideal for continuous scanning applications over a large frequency range. On the other hand, when high stability is required in the long-wavelength range, the CatEye configuration is effective.
-
<Optimized for blue to near-ultraviolet region> It is optimized for operation in the wavelength range of 369 to 500 nm, demonstrating excellent performance in the short wavelength region where achieving a stable and wavelength-variable light source is challenging.
-
<High Stability Monolithic Structure> By adopting a monoblock cavity machined from an aluminum block, we eliminate individual components that are sensitive to vibrations. This achieves excellent vibration resistance and high reproducibility, while also reducing sensitivity to acoustic noise.
-
<Wavelength tuning without the need for realignment> By separating the vertical alignment and the rotation mechanism of the diffraction grating in the design, smooth wavelength tuning over several tens of nanometers is achieved without the need for realignment.
-
<High-Precision Applications with Narrow Line Width Characteristics> In the long wavelength range, a typical line width of below 100 kHz is achieved, and in the blue region, approximately 200 kHz, catering to applications that require high-resolution measurements.
-
<Long-term Stability through Semi-Hermetic Structure> The semi-hermetic structure minimizes the impact of external pressure fluctuations, achieving high stability over a long period.
-
<Compact Integrated Control Option> The LDX/LDF models support integration with built-in optical isolators and small laser controllers (mLC). This enables a compact all-in-one laser solution compatible with USB or TCP/IP control.
