Supports the transmission of optical signals over a larger range of incidence angles.
Standard TO46 compatibility:
Used together with standard TO46 headers.
Optical communication:
Used for lasers, detectors and other TO46 packages.
Optoelectronic sensing:
Suitable for optoelectronic sensors and infrared detection.
Consumer electronics:
Used for compact packaging of various optoelectronic devices.
Distinctive water-drop optical design:
A unique optical solution combining light focusing with a wide acceptance angle.
High optical coupling efficiency:
The water-drop ball window improves the transmission and convergence efficiency of optical signals.
Mature process platform:
Manufactured on a mature glass-to-metal sealing platform.
The water-drop ball window cap provides an optical channel for the internal elements through its water-drop-shaped spherical window. The curvature of the spherical window converges the transmitted beam, while the water-drop shape enlarges the effective receiving angle of the window, allowing optical signals from different directions to enter the detector efficiently or making the emitted light more concentrated. After the cap body is welded and sealed to the header, the internal chip is isolated from the external environment, with electrical interconnection completed through the pins. The optical parameters of the window can be optimized through design to meet application requirements.
