WPM-10-4P: High-Accuracy Quartz Waveplate
The WPM-10-4P quarter-wave plate delivers a retardation accuracy of λ/100 and an outstanding surface flatness of λ/10, enabling precise control of circular or elliptical polarization states. Manufactured from crystalline quartz and coated with a multilayer broadband anti-reflection (AR) coating, it maintains transmission above 98 % from 400 nm to 700 nm. Its low sensitivity to mechanical stress and humidity ensures stable performance in laboratory and industrial laser setups, including high-power femtosecond systems and polarization-sensitive imaging.
OSK-6328-18: Stabilized Helium-Neon Laser
The OSK-6328-18 is a class II, 1.8 mW HeNe laser that provides a single-mode, TEM00 output at 632.8 nm with a coherence length exceeding 20 cm. A built-in power supply and active cavity stabilization maintain intensity noise below 0.5 % RMS, supporting precision tasks such as holography, metrology, interferometry, and calibration of spectroscopy instruments. The rugged aluminum housing and long-life discharge tube (>20,000 hours) allow continuous operation with minimal maintenance.
ANDY-20C-25: Narrowband Optical Filter
Engineered for demanding spectral isolation, the ANDY-20C-25 dielectric interference filter provides a 20 nm full-width at half-maximum (FWHM) bandwidth centered at 532 nm with an optical density (OD) > 6 for excellent out-of-band rejection. Its hard-oxide coatings resist humidity and laser damage, while the 25 mm diameter ensures compatibility with standard optical mounts. This filter is ideal for fluorescence microscopy, Raman spectroscopy, and laser-line cleanup where sharp wavelength selectivity is critical.
PBS-15-4579: High-Performance Polarizing Beam Splitter
The PBS-15-4579 cube beam splitter provides a 15 mm aperture and achieves an extinction ratio exceeding 1,000:1 while maintaining transmission above 95 % for p-polarized light over the 450 nm - 700 nm range. Its precision optical contacting eliminates glue interfaces, reducing absorption and enabling high-power laser handling up to 10 J/cm². This makes it a top choice for laser power balancing, Mach–Zehnder interferometers, and polarization-entangled photon experiments.
RSPMF-10: Precision Thin-Film Polarizer
The RSPMF-10 thin-film polarizer features a 10 mm clear aperture with an exceptionally high extinction ratio (>2,000:1) and a damage threshold greater than 15 J/cm² for nanosecond pulses. Optimized for 532 nm and coated for low absorption (<0.1 %), it is well suited to high-power Nd:YAG laser systems, optical isolators, and beam-combining applications. Its low wavefront distortion (<λ/8) ensures beam quality preservation in sensitive quantum and ultrafast experiments.
Together, these components underscore OptoSigma’s commitment to advancing optical performance and photonics integration. By offering premium waveplates, lasers, filters, beam splitters, and polarizers engineered for accuracy, durability, and stability, the company enables scientists, manufacturers, and system designers to achieve new levels of precision and productivity in next-generation optical systems.
