The present invention relates to a variable angle of incidence, the wide-angle surgical illuminator. Towing one aspect of the present invention a small-gauge, variable angles of incidence for one trillion people surgery system includes: a light source for providing a light beam Optically coupled to said light source to pass under the light (optically coupled) optical cable The fiber optic cable operatively connected to the handpiece Operably linked to an optical fiber to the handpiece, wherein the optical fiber is being passed and the light are optically coupled to the optical cable The optical fiber optically connected to the distal end of the optical assembly to provide the light receiving said light for illuminating the region And receiving the optical assembly, and (housing) by the operation for illuminating the selected area, such as a surgical site, the handpiece and cannula operatively connected to said optical assembly. Optical assembly fiber / polymer-dispersed-liquid-crystal ("PDLC") may include a diffuser / glass needle or nested compound parabolic concentrator ("CPC") cone. PDLC in the diffuser / glass needle embodiments, 0.50 NA fiber or standards that have similar values endo-illuminator can be an optical fiber. The light from the light source is transmitted by the optical fiber is provided in a PDLC diffuser for further transmission and the diffuser of the light. PDLC diffuser amount of sunlight in the diffuser can be controlled electrically and can be varied to the extent of the diffuser highly diffused from no. After passing through the PDLC diffuser, the light beam passes the beam, for example a needle or optical fiber for illuminating a desired area, such as a surgical site in the eye (e.g., glass) to provide a.본 발명은 가변성 입사각, 광각 수술용 조명기에 관한 것이다. 본 발명의 한 구체예인 작은-게이지, 가변성 입사각 조명 수술용 시스템은 다음을 포함한다: 광선을 제공하기 위한 광원 상기 광선을 받고 전달하기 위해 상기 광원에 광학적으로 연결된(optically coupled) 광케이블 상기 광케이블에 작동 가능하게 연결된 핸드피스 상기 핸드피스에 작동 가능하게 연결된 광섬유, 여기서 상기 광섬유는 상기 광케이블에 광학적으로
