LIGHT EMITTING DEVICE INCLUDING LIGHT-TRANSMISSIVE MEMBER AND LENS MEMBER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18517409 titled 'LIGHT EMITTING DEVICE INCLUDING LIGHT-TRANSMISSIVE MEMBER AND LENS MEMBER
Simplified Explanation
The patent application describes a light emitting device that includes a semiconductor laser element, a base member, a light-transmissive member made of sapphire, and a lens member.
- The light emitting device includes at least one semiconductor laser element.
- The device has a base member where the semiconductor laser element is placed.
- A light-transmissive member made of sapphire allows laser light to pass from the lower surface to the upper surface.
- A lens member, fixed to the base member or the light-transmissive member, helps transmit the laser light.
- The incident surface on the light-transmissive member is an a-plane of the sapphire.
Potential Applications
The technology can be used in:
- Laser cutting and engraving machines
- Medical devices for surgery
- High-speed data communication systems
Problems Solved
- Improved transmission of laser light
- Enhanced durability and heat resistance due to the sapphire material
Benefits
- Higher efficiency in light transmission
- Longer lifespan of the device
- Better performance in high-temperature environments
Potential Commercial Applications
Optimizing Light Transmission with Sapphire Light-Emitting Device
Possible Prior Art
There may be prior art related to the use of sapphire in light-transmissive members for laser devices.

Original Abstract Submitted
A light emitting device includes: at least one semiconductor laser element; a base member on which the at least one semiconductor laser element is disposed; a light-transmissive member including: an upper surface, a lower surface, and a light-transmissive region through which laser light emitted from the at least one semiconductor laser element is transmitted from the lower surface to the upper surface; and a lens member through which the laser light emitted from the at least one semiconductor laser element, the lens member being fixed to the base member or the light-transmissive member. At least the light-transmissive region is made of sapphire. The light-transmissive member includes an incident surface on which the laser light is incident, the incident surface being an a-plane of the sapphire.
