Refractor

$Robótica | Telescopios refractores$ Un refractor es un telescopio con una lente frontal que capta la luz incidente y la converge hacia un punto focal mediante refracción. Existen básicamente dos tipos de telescopios refractores: acromáticos y apocromáticos.

Los refractores acromáticos tienen un diseño de lente dual. Los acromáticos pueden sufrir la llamada aberración cromática, que se asemeja a pequeños arcoíris alrededor de objetos brillantes como la luna y las estrellas. Esto se debe a que este sistema no puede enfocar todos los colores del espectro en el mismo punto exacto. Nota: esto no es ni bueno ni malo; es una característica natural de este diseño. Los refractores acromáticos generalmente son adecuados para observaciones visuales con aumentos limitados. Son menos adecuados para la fotografía.

Los refractores apocromáticos tienen un diseño de lente compuesto por tres o más elementos. Esto permite que toda la luz se enfoque exactamente en el mismo punto. Esto los convierte en un sistema con corrección de color. Los apocromáticos son ideales para observaciones visuales y astrofotografía.

Todos los telescopios refractores tienen un plano focal curvo. Visualmente esto no supone un problema, pero fotográficamente debe corregirse con un corrector óptico llamado aplanador de campo .

¡En esta sección encontrarás todos los diferentes tipos de telescopios refractores!
