Resumen
En esta contribución, presentamos un estudio conciso y educativo de lentes gravitacionales debido a distribuciones de masa transparentes. Nos enfocamos en los cálculos de las propiedades de la imagen para perfiles de masa idealizados, incluyendo la esfera transparente uniforme, la esfera de gas isotérmico, la esfera de gas isotérmino no singular, y el perfil de King transparente. Utilizando técnicas numéricas y el software XFGLenses, se calculan y se visualizan las imágenes resultantes, junto con las curvas críticas y cáusticas asociadas. Los resultados son consistentes con las predicciones teóricas de los lentes transparentes, como lo son un número impar de imágenes, y la reducción del número de imágenes en dos cuando la fuente atraviesa la cáustica. Las geometrías que presentan las curvas cáusticas encontradas incluyen la forma de diamante, forma elíptica, y tipo lemniscata. Entre las curvas críticas, formas elípticas fueron las más encontradas, y la forma tipo lemniscata aparecieron específicamente en el case de la esfera isotérmica no singular, lo cual es esperado de lo conocido de lentes gravitacionales debido a distribuciones ideales.
