ファーストメカニカルデザイン List of Products and Services

The "FA1000S_θ" is a device designed to couple a laser beam propagating in free space into an optical fiber after passing through an aspheric lens, developed with the full cooperation of Professor Akira Furusawa's laboratory at the University of Tokyo. It features a two-axis θ adjustment mechanism that allows for independent adjustment of two orthogonal rotation axes without moving the fiber's entry point from the center of the sphere, thanks to specialized processing technology (spherical gimbal mechanism). This new mechanism simplifies alignment, which was previously very difficult, and ensures long-term stability. 【Features of the θ Axis Adjustment Mechanism】 ■ Spherical Gimbal Mechanism (Patent No. 5888775 granted) - A structure where the fiber's entry point aligns with the center of the spherical rotating element due to specialized processing technology. - The entry point experiences minimal positional shift even when angle adjustments are made. ■ High operability and long-term stability achieved - Adjustment screws use a fine pitch screw with very little backlash of 0.15mm. - Our unique soft lock mechanism provides high holding power after adjustments. *For more details, please download the PDF (English version) or contact us.

The "FBP1000S" is a reproducible plate characterized by its ability to maintain almost no deviation in the interferometer even when the mirror mount is removed and reattached in a Mach-Zehnder interferometer. The visibility after installation is also very stable, and we will attach reproducibility and stability data specific to each product at the time of shipment. [Usage Example] ■ Common use of upper plates is possible <Example> By preparing multiple units and adjusting mirror mounts equipped with various types of optics (such as mirrors and beam splitters), you can introduce changes to the optical path (the reproducibility is perfect regardless of which upper plate is removed or attached). *For more details, please download the PDF (English version) or contact us.

The "MH100IH_254" is a mirror mount developed based on the manufacturing know-how of the MM1000S, with an optical axis height of 1 inch. Its compact size does not take up unnecessary space, making it useful. Additionally, it is equipped with ultra-fine adjustment screws with a pitch of 0.15mm, similar to the MM1000S. If there is enough space, further fine adjustments can be made by attaching an over knob. 【Specifications】 ■ Material: Super duralumin ■ Surface treatment: Matte gray anodizing ■ Maximum thickness: 33.8mm ■ Weight: Approximately 87g (excluding mirror weight) ■ Mirror diameter: φ1” thickness = 5–9.5mm (maximum approximately 15mm) *For more details, please download the PDF (English version) or contact us.

The "MH050IH_127" is a 1/2 inch mirror mount that can be used for transmission (straight line: φ11.2). The fixing screw allows for the rotation direction to be changed arbitrarily and secured, as there is only one mounting bolt. Additionally, since the contact surface is made of resin (POM), it can be secured without damaging the mirror. 【Specifications】 ■ Material: Super Duralumin ■ Surface treatment: Anodized (matte/gray) ■ Maximum thickness: 28.1mm (standard adjustment position: 1:30) ■ Weight: Approximately 49g (excluding the weight of accessories such as mirrors) ■ Mirror diameter: φ1/2” thickness = approximately 3 to 6.35mm *For more details, please download the PDF (English version) or contact us.
