Cemented doublet lens
Optical Lenses
Astarphotonics
材料: BK7 glass + ZF2 or ZF4 焦距（EFL）: ±2% 尺寸公差: +0 / -0.18 mm
Cemented lenses minimize or eliminate chromatic aberration. Their achromatic design also helps minimize spherical aberration. Achromatic lenses suit applications such as fluorescence microscopy, image relays, inspection and spectroscopy. They are manufactured by cementing two or more elements together and can form smaller spots than singlet lenses.

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.
