Low-order waveplate
Waveplates
Astarphotonics
材料: Quartz 尺寸公差: +0.0 / -0.1 mm 表面质量: 20/10
Chenzheng Optoelectronics supplies precision low-order, zero-order, dual-wavelength and achromatic waveplates. Low-order waveplates introduce multiple orders of retardation, offering good mechanical strength and high laser damage thresholds. Retardance accuracy is slightly lower than zero-order plates, but lower prices provide good cost performance.

Dual-wavelength waveplate
Waveplates
Astarphotonics
材料: Quartz 尺寸公差: +0.0 / -0.1 mm 表面质量: 20/10
Astarphotonics offers zero-order, low-order and quartz multiple-order waveplates. A cemented zero-order waveplate consists of two multiple-order waveplates joined by cementing or optical contacting. Their thickness difference equals the thickness of a single true zero-order waveplate, and their fast axes are perpendicular. Zero-order waveplates produce zero-order phase retardation and outperform multiple-order waveplates, with broader bandwidth and lower sensitivity to temperature and wavelength changes.

Achromatic waveplate
Waveplates
Astarphotonics
材料: Quartz, magnesium fluoride (MgF₂) 尺寸公差: +0.0 / -0.1 mm 表面质量: 40/20
Achromatic waveplates consist of birefringent crystals of two different materials. Their different dispersions enable relatively uniform phase retardation over a broad wavelength range. Achromatic waveplates are also relatively insensitive to temperature.

As a professional ultraviolet‑laser solution provider, Precilasers has launched its 266 nm narrow‑linewidth industrial laser, delivering reliable single‑frequency output for high‑precision interference lithography, semiconductor inspection and precision metrology applications.
Ytterbium‑doped fiber serves as the core energy‑conversion component inside a fiber laser. Pump light emitted by laser diodes is coupled into the gain fiber, and energy is transferred to signal laser beams via ytterbium ion energy‑level transition for power amplification. Two dominant pump wavelengths, 915 nm and 976 nm, have been widely adopted over decades. With the rapid progress of pump chip and wavelength‑locking technology, 976 nm edge‑emitting laser (EEL) pumps have gradually surpassed the 915 nm route and become the new industry mainstream. Shenzhen Lemon Photonics Technology Co., Ltd keeps developing high‑performance pump chips for fiber laser manufacturers.
Driven by fast‑growing demands of 3D perception, biometric authentication and machine‑vision industries, near‑infrared imaging optics have become a vital hardware component for intelligent sensing systems.
The ElFys PD25s series photodetectors adopt ElFys‑patented Black Silicon Induced Junction technology, delivering excellent spectral response spanning deep‑ultraviolet, visible and near‑infrared bands for diverse high‑precision photometry applications. Sub‑variants including H, M, HG and MG are optimised for low‑capacitance, low‑dark‑current and high‑reverse‑bias guard‑ring operations respectively. Multiple packaging configurations are available to satisfy various system‑design requirements.
